Fix the password search icon and view layout

The "ifRoom" property doesn't work properly with action views as the
main item will not collapse in that case and just move the option to
the settings menu.
Using "always" (like Site Settings does it) fixes that issue.
Removing the previously used "collapseActionView" prevents filling
the entire action bar which fixes layouting on large screens.

All other changes ensure no regressions although we now have to rely
on different Listener methods and UI interaction flows.
