Generating message preview on the fly (#645, #754)

[alwx]

In order to fix #645 we needed to change the way we do rendering, because it is almost impossible to translate the content that was pre-rendered before and saved to database.
This PR introduces the new way of rendering — I've removed :preview and :rendered-preview from the message model and made the process dynamic. And since the rendering became dynamic, we can easily translate almost everything every time we need.

Fixes #645, #754

Instead of specifying this information here we could get it from parameters here https://github.com/status-im/status-react/blob/8663bdfada6f1d7690a6fb0ab1a88236eaef0e34/src/status_im/chat/handlers/send_message.cljs#L286-L286
Command's name can be found in the same map as chat-id and command, the path is [:command-name :command :name].
It would be great to start using specs there, but that's not objective of this PR.

@rasom done, no more contentCommand in js file

[rasom]

That's how it looks on device#1:

on device#2:

on device#1 after reloading:

Both iOS, device#1 English, device#2 Russian

@rasom I've updated the code. Please, check it now.
Please also note, that we now perform a jail call, so if there is a problem with jail, there also may be problems with message content.

One more thing here: amount is shown in different formats on the same device, but I suppose it should be unified for the specific localization

should we fix this too, @alwx, @jarradh ?

yes it's supposed to be regionalised.... didn't we have an issue for this?

[rasom]

That's what #754 is about, thanks.

[alwx]

@rasom how can I reproduce this bug?

[rasom]

I was using two devices: the first Android with English and the second iOS with the Russian language. Then I just sent some ETH between them.

Phew, it was hard :(

1. Our i18n library doesn't support a localization of numbers. There is a function called I18n.toNumber, but it doesn't automatically add correct delimiters and separators;
2. The solution for Web is to use something like Number(100000).toLocaleString("ru-RU"), but it doesn't work in Safari and WKWebView because Safari doesn't support any arguments for toLocaleString (https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString#Browser_compatibility).

The final solution works, but it is a bit hacky — I use toLocaleString() for a pre-defined number and extract delimiter and separator (status-im.i18n, line 78) to use it later.

@alwx, does this issue #779 mean that this will be fixed in another PR?

[alwx]

@rasom it means that the code for generating preview messages in chat list will be rewritten and moved to JS. So I decided not to pay too much attention to this problem here because it will be reimplemented anyway.
