Switching away from an empty branch errors

[MariusDoe]

When currently on a branch without any commits (such as the initial master branch), trying to switch to another branch produces this error: MessageNotUnderstood: UndefinedObject>>includesObjectAt:. This is due to self loadedHistorian version being nil, as the branch the browser is coming from is empty.

Steps to reproduce

• Create a new project (this creates an empty master branch).
• Add a remote and fetch it. This one works for the reproduction.
• Right click one of the remote branches and select "Create a new branch and switch to it".
• Name the new branch something other than master.
• Now, the error MessageNotUnderstood: UndefinedObject>>includesObjectAt: should appear.

Thank you for the report. To remember to handle branches without commits is always a pain... I will write a test case that tests the two switch variants while on an orphaned branch.

@MariusDoe Please update to the latest version on the develop branch and check whether the issue is resolved. If it is not, please reopen.
