force close prompt regression

[Roasbeef]

In the application, when a user goes to close a channel that's inactive, in the past we would warn them that they would incur a delay (we even know exactly how long it'll take and should expose that). Today with the latest version of the application, there's no such prompt and a force close happens silently in the background. This exacerbated by the fact that we don't show any sort of time estimate (#525) for close close channels. As a result, a user ends up in a case where their funds are now in limbo without their explicit awareness, with no clear indication w.r.t when their funds will be available again.

#525 is already in the todo column on the board. There is also #912 which we need to address.

What do you mean by regression? We haven't had a prompt warning of a force close in the app yet.

Oh, I thought we did in the past? Or maybe it was just part of the design on invision but never got fully integrated. Either way we've discussed the need for it, so just wanted to write it down in the issue tracker so we don't forget about it.

Seeing users run into this more frequently.

Example scenario: they see a channel pending open for "a while", then decide to close it. This does a silent force close behind the scenes, causing their funds to be locked up for a period of time that scales with the size of the channel.

In the above scenario, it's likely the case that block confirmations were coming in slowly, but the user got impatient. If they knew that this would cause their funds to go into limbo, then they are more likely to just wait.

A related UI tweak is to show a progress indicator for "pending open channels", so users know that the process is moving forward.
