Fix Enter to finish session in more cases

Detect the Enter key to finish a session not only on KeyEvent:s,
but also when the IME uses InputConnection.commitText() to send
\n. This seems to be triggered more after switching to the Uri
input type. Closes #124

Also bump app version for a quick release.
