- Do not attempt to get studies metadata if ViewerData already has studies property and use it to view studies in tab (for cases when a tab is opened with metadata externally)

- Add showStudyListTab helper whether to show StudyListTab in worklist template - it is shown by default (it is not shown only if "data.showStudyListTab" is set to false when rendering worklist template)
