Fix Ctrl + F not working

Fix Crtl + F not working by only having the shortcut assigned to a single searchfield. 
- Ctrl + F is now for the roomlist search
- The user search in the room drawer is now ctrl + shift + f
- for the emoji picker and qucik switcher these have the shortcut removed and focus is managed by the popup.
