To reproduce:
1) Open 2 toplevel projects, e.g. analogclock and calendarwidget from inside qt/examples/widgets/
2) Notice, that current project is calendar widget, as it was opened as a second project (marked with bold in project explorer).
3) Double click on analogclock.cpp so that the file will appear in editor
4) Go to Tools | Git | Current Project. All submenu items refer to "analogclock", which is not the current project (bug).
5) RMB over analogclock project inside project explorer -> Set "analogclock" as active project.
6) RMB over calendarwidget project inside project explorer -> Set "calendarwidget" as active project.
7) The state of Qt Creator GUI should be the same as in point 4. Redo the point 4 - now submenu items refer to "calendarwidget" - which is expected behaviour.
