• Finishing Pipeline Activity Widget.
• Migrating the DashboardGraphs (now renamed to DashboardWidgets) to typescript.

• Fixed some types in api after realizing some typescript issues with : Branches mock.
• Added some new functions on DashboardWidgetWrapper utils to help with time.
• Removed noBuildsFound case because I believe it was unnecessary.
• HOC withDashboardNotReadyHandler was created because it will be necessary to do it with CostDashboard as well later.

• Removing Dead code.
• Fixing places where dead code was being used (CycleTimeAndDefects).
