Make sure version is created before deployment

Short version:
This is needed to assure that our deployment works correctly when it comes to keeping the version the same on our targets.

A little longer version:
Without this and if the executer's enviroment has the KEEP_VERSION set to 'true', the last-version file is deleted in deploydev proccess and never re-created, hence resulting in an unkown version in the snapshot, which results a re-creation of the version on each target.

Note: today's deploy was done 'manually' to avoid this problem.
