#42 - Maintenance branch creation does not try to update just created branch.

Browse Source 
Introduced an overload for GitOperations.checkout(…) to allow to define whether a branch about to be created is supposed to be updated right away. The already existing method keeps the old behavior (immediate update) while the maintenance branch creation forces a create only as by definition a branch about to be created is not going to be available in the remote repo.
