Creation of hidden repositories listed on page of a team account (BB-5954)

Assume that A and B are a members of the team T.
B creates a repository under the account of T. Said repository will be reachable through https://bitbucket.org/T/newrepo. Team member A may not access newrepo at all, whether read nor write nor admin.

If A checks https://bitbucket.org/T/ now, the creation of the repo is visible to A, even though (s)he has no access.
