Refresh option not available for some resources that are not closed projects #2538

Update javadoc for ResourceMgmtActionProviderTests.java

Change made since the fix to #1438 unintentionally removed the "refresh" contextual menu for resources that are not projects.

With this change the "refresh" contextual menu is shown if ANY navigator selection is either (A) an open project, or (B) a non-project resource. Put another way: the 'refresh' item is NOT shown if ALL selections are closed projects.

Fixes #2538
