i3 - improved tiling WM

Bug fix: Call clear_input() when the password is wrong.

Patch status: merged

Patch by oblique

Long description:

clear_input() calls start_clear_indicator_timeout() to clear the
indicator after 1 second. This had as a result the screen to be cleared
when the "verifying…" message was showed, so the "wrong!" message didn't
show up when the password was wrong.
