[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. Yes I tried with your branch. I am giving here one way of reproducing.
Steps to reproduce
1.open contextual popup sample
2.tap on "DIRECTION" button(popup opens)
3 use 5 way to spot "DIRECTION" button.(popup is still open)
4.press "Enter" on "DIRECTION" button
Result
with current master branch :   popup closes
with https://github.com/enyojs/moonstone/compare/BHV-15343-aarontam .:: popup doesn't close
This is the behavioral difference I was mentioning in my previous comments.
Can you reproduce this?  please comment.
Thankyou.
