Repository is now instanciated on the fly

[abienvenu]

No more repository instantiated in constructor of ClientManager and TokenManager.

This avoids a database connection to be established for every request.

Fixes issue https://github.com/FriendsOfSymfony/FOSOAuthServerBundle/issues/422

Tests are failing tho

[abienvenu]

Right, there was a test conflicting with the very purpose of this pull request. I removed this test. There are still some failing tests, but I guess these out of memory errors are unrelated.

The unit tests have improved greatly the last couple of weeks.

Could you rebase on top of master?

[abienvenu]

Ok @dinamic , I made the rebase and tests are fine now.

Can you handle authcodemanagers too?

[abienvenu]

Yes @dkarlovi, good point. AuthCodeManagers are handled as well now.
