Adding issue contextual bar

[henit-chobisa]

Closes #94

Issue(s)

We have a button in UserProfileView, which tends to open user's issues, with it's states of mentioned / created and open / close, but the supporting SurfaceView that lists the issues is a ModalView which is not the best solution to display list like data, hence I request to switch to Contextual Bar View, which doesn't block user's activity while working on any chat and keeps the issues handy in contextual bar.

Acceptance Criteria fulfillment

• [x] Replace UserIssuesModal with UserIssuesContextualBar under a new Directory with Contextual Bars.
• [x] Update ContextualBar Actions that updated the Current Modal to updating the current contextual bar.

@henit-chobisa Why does this completely remove userIssuesModal and if it does, did we check for backward compatibility incase the modal was being used elsewhere ?

@samad-yar-khan, I have checked all the places where the userIssuesModal is used and modified it to the contextual bar. So far, I am sure that the userIssuesModal has not been used anywhere except the profile view, If you say, I can still keep a copy of userIssuesModal for backward compatibility ?
