Android: Hide vkb when IM disabled for focus object

When the focus object changes to an object that does not have
IM enabled, we should hide the keyboard instead of resetting it.
This happens, for instance, if you change to a different tab in
an application while a text input in the previous tab had focus.
Previously the input panel would stay open and overlap part of the
new tab.

[ChangeLog][Android] Hide input panel when focus changes to an
object that does not accept input.
