Contacts: will pop up "Unfortunately, contact has stopped.".

In ContactEditorActivity, when long press name information in
AddLocalGroupDialog, SoftInput board and action bar were shown.
The rotation of screen caused ContactEditorActivity to recreate
and dismiss AddLocalGroupDialog. Then SoftInput board and action
bar lost their dependent view.
At last, the crash happend.

Through adding 'android:configChanges="orientation|screenSize
|keyboardHidden|locale"' into AndroidManifest.xml to avoid the
recreate-operation of ContactEditorActivity.
