Issue with using sourcetree with gerrit

[mikaeldubois]

please see https://jira.atlassian.com/browse/SRCTREEWIN-12850

for details and affected versions.

brief summary is every version > 3.1.3 on sourcetree for windows using system or embedded git does not allow for pushing of code changes because the window lists nothing since remote refs/for branches do not actually exist at the time of pushing.
