[BHV-15343]Contextual popup doesn't work properly when hide() from appli...

...cation side

Issue: When contextual popup is closed from application side, it doesn't
update some properties properly which causes this behavior
Fix: control's hide() method is overridden in  contextual popup to
update the properties properly.

hi @aarontam I tried this approach earlier, it works fine but it conflicts the earlier behavior
>> we cannot close a contextual  popup by pressing "Enter" on the popup button , with the changes in https://github.com/enyojs/moonstone/compare/BHV-15343-aarontam .
I don't know which is the correct behavior earlier or present.
Thankyou.
