Added function to 'lazyload' the repository

[winus]

Yesterday while running automated test after merging our FOSOAuthServerBundle branch in our project we ran into a problem; unable to execute any command when there was no database available yet.
Our test environment script delete the database and creates is again with settings from the parameters.yml. ( plain doctrine command app/console doctrine:database:create etc.)

All commands would fail because the database would not exist. Even just a app/console.

After debugging narrowed it down to the ClientManager.php and the TokenManager.php which get a repositoryClass from doctrine. Doctrine tries to generate some meta data for the requested class.

Solution:
Moved the constructing of the repository from the constructor to a separate function. And altered some lines that used the property to use the function instead.

Stack trace:

[PDOException]
SQLSTATE[HY000] [1049] Unknown database 'ris_testing'

Altered the tests to pass. Don't know if this is enough.

#574 Seems to have about the same fix

[GuilhemN]

There is a line break missing :)

[GuilhemN]

Same here

[GuilhemN]

Closing in favor of #574, thanks!
