Fix a race when an editText was removed and added immediately again

In some rare cases, the hide request that was triggered by removing a view was applied in InsetsController too late. A following show request could have been applied before, resulting in the IME not being shown.
This was caused by InputMethodManager, as some methods (e.g., closeCurrentInput()) did not call into InsetsController#hide, but into IMMS.

This CL fixes this race condition by calling directly into InsetsController#hide, instead of using IInputMethodManagerGlobalInvoker.
