Show incompatible projects in Bitbucket import status
What does this MR do?
This MR displays incompatible Bitbucket projects (e.g. SVN, hg) in the status table.
Why was this MR needed?
Users are confused when they don't see projects show up. The import list should show incompatible projects as we do for Google Code to make it more obvious to the user what is happening. (See !586 (merged) and 9c76a6fa).
