On screen keyboard opens every time you tap on a channel on mobile

Describe the bug
Every time you tap on a channel, fermi opens the on screen keyboard for some reason.

This seems to be a focus issue where since using the swipe gesture to leave a channel does not unfocus the text box, opening another channel will bring up the keyboard immediately.

At the moment you can manually focus something else (tapping the mobile back button, selecting a message, or similar things) after sending a message, and that should keep the keyboard from popping up while you're browsing channels (until you next send a message).
