ibusManager: Close candidate popup upon engine change

The IBusCandidatePopup can get 'stuck' in an active, visible state if
it is on-screen at the point when the input method is changed to a method
that doesn't use such popup (e.g. regular English).

Force the candidate popup to close when the engine is changed.
It will reappear (via regular lookup table update signal) if/when it is
next required.

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6717
