XNAT-4457 Fixed bug where admins could not approve PARs when users with some level of all data access requested access to projects. Once I fixed that I noticed that the admin was being directed to the project page with the actions box in the wrong place. I fixed this by no longer adding topTab (which seems to be deprecated) to the context.
