Using !raid to convert egg to hatched doesn't work

[wdbrs]

Background:
Someone reported an egg when they should have reported a hatched raid, I was trying to correct it.

Readme says:
!raid
->Converts raid egg to an open raid.

Result:
Meowth! Please wait until the egg has hatched before changing it to an open raid!

Workaround:
The only workaround is apparently to use "!timerset 0" to hatch it, then another timerset to set the raid expiration time. This usage of timerset is not properly documented either though, for that it says only, "Set the expiry time for the raid" in the readme
