project: Optimise GetCommitRevisionId when revisionId is set
When comparing 2 manifests, most of the time is
spent getting the relevant commit id as it relies
on _allrefs which ends up loading all git references.
However, the value from `revisionIs` (when it is valid)
could be used directly leading to a huge performance improvement
(from 180+ seconds to less than 0.01 sec which is more
than 25000 times faster for manifests with 700+ projects).
