Override before_script for sourcing autodevops
Because the originating branch could have been deleted by the time the stop review jobs run, we had to set the GIT_CHECKOUT to false and check out master to access the autodevops functions.
We now see an issue where it says the autodevops file does not exist because when the before_script is called, it's operating in an empty repository.
This change causes the job to wait until master has been checked out to source the autodevops script.
Closes #2240 (closed)
