LatinIME: Fix back-arrow finishing activity
* When going to a sub setting menu and pressing the
action bar up arrow instead of the device's back
key, the settings are closed instead of going
one level up as expected
* Call "onBackPressed" instead of "finish" to fix
that
* For InputMethodSettings create a new flag to
alter the behaviour for our use case but to keep
existing behaviour for other callers
Test:
- Open the keyboard settings from Settings app
and navigate between menus ->
action bar back icon only goes one levelup
- Open keyboard settings directly from keyboard:
behaviour is the same, last "up" action takes you
back to where you came from
