Show repos on the dashboard with owner/reponame instead of just reponame (BB-4117)

• 2 users: user1 and user2
• user1 create git repo repo1
• user1 give acces to that repo1 to user2
• user1 make some commits on repo1 (this appears on the dashboard of user2 with link ../user1/repo1)
• user2 create his own repo with the same name repo1
• user2 make some commits in his repo1
• user1 make some commits in his repo1
• user2 pull this commits in his repo1 and push it
• user2 now see on the dasboard links like that: user1 commited to ../user2/repo1 (but user1 dont commited on user2/repo1, he commited on user1/repo1)

It's not so bad bug but it's confusing
