On Ubuntu, when 'Add CC' was clicked, both the cc suggestions and
reviewer suggestions opened simultaneously.
Then the reply dialog opens, _handleReplyOverlayOpen is called from the
change view. That ends up triggering _focusOn (in the reply dialog) on
the reviewers input. _focusOn is called a second time, to focus on the
CCs, but since the _focused attribute for the initial autocomplete was
not removed, they both remain open.
This change fixes the issue by removing the focused attribute on
gr-autocomplete when _onInputBlur is called.
