Title: Added branch-alias to version output when it is aliasing dev-master

Added branch-alias for dev-master to ```--version|-V``` output when current version is actually a revision (a non release/git tag).
This replays the work done in #3352 taking care about other uses of ```Composer::VERSION``` constant (for instance ```diagnose``` and ```self-update``` commands).
