Fix IME keyboard issue for url bar of mini browser

Fix IME keyboard issue for url bar of mini browser

There are 2 issues:

1. When IME keyboard is hidden by the outside, focus of url bar is not
removed. So when user tries to tap on url bar, IME keyboard is not
shown.
For resolving it, we should remove focus of url bar when callback of
ECORE_IMF_INPUT_PANEL_STATE_HIDE is called without hide_imf_panel()
call.

2. Sometimes IME is closed before it is hidden. So We cannot move tool
box and remove focus of url bar.
Solution is that move tool box and remove focus when IME close callback
is called.
