[JENKINS-29301] Git plugin falls into a infinite loop on unspecified branches containing / after force push

An unspecified branch may sometimes contain a slash '/' which causes the method DefaultBuildChooser.getCandidateRevisions() adding the branchSpec as a local reference.

This together with a force push by someone which changes the parent of the latest commit will cause an infinite build loop based on 'Multiple candidate revisions'.
