Instead of focusing the composer, focus the buffer scrollview when switching to a buffer. This allows keyboard navigation to work as expected, with arrow up/down and page up/down scrolling the buffer instead of doing nothing. Focus back the composer when a KeyboardEvent produces text. This allows users to start typing a message right after switching to a buffer. Closes: https://todo.sr.ht/~emersion/gamja/64
