No InCall UI visible after hiding conference manager.

- The hide of the conference manager fragment and subsequent show of the
call card was being done inconsistently in a few places.
- Added a new method to hide/show the conference manager fragment and
the call card at the same time and replaced all references with this new
unified method.
