Master branches are always unknown

[ErikJanssonWork]

I have set up several projects now and they all have unknown master branches in this plugin. When I look in bitbucket I see that they in fact are named "master".

As you can see, in build history there is no master branch name, isn't it?
So TC does not parse the branch name and does not provide it to plugins.

You should configure branch specification as described https://confluence.jetbrains.com/display/TCD10/Working+with+Feature+Branches#WorkingwithFeatureBranches-Logicalbranchname
