SSH submodule not rendered as link due to different hostname between HTTP and SSH URL

Steps to reproduce

1. Setup an apache server with the URL http://apache.server.com/stash (Apache located in different server)
2. Set Base URL in Stash as http://apache.server.com/stash
3. Set SSH base URL in Stash as ssh://localhost:7999
4. Add SSH submodule ssh://git@localhost:7999/tst/test.git into another repository http://apache.server.com/stash/projects/TST/repos/test2/browse
   (The SSH submodule folder is not rendered as a link)
5. Change Base URL in Stash to be http://localhost:7990/stash
   (The SSH submodule folder in test2 repository is rendered as a link http://apache.server.com/stash/projects/TST/repos/test/browse)
