Support alternative default brach for gerrit

PRE 2 weeks ago 0

Please add support to change default Gerrit branch. Current default in SmartGit is `master` which is used when branch has no tracking target, but that may lead to issues when default branch on Gerrit side is named differently, eg.: `main`.

It becomes tedious when I want to have several temporary branches with different history for the default branch (all require me to setup the tracked target branch).
