Currently when a user doesn't have permissions to commit or create a
merge  request in a project we offer the user the option to fork the
project when opening the Web IDE. However, if a user already has a fork
then we open the upstream project and not the forked project in the
Web IDE. This means users are "doomed to fail" as they won't be able
to make changes, or save their changes and make them in the
appropriate context.
