Git branch dialog is not being updated when rebasing

1. Have a git repository with some commits.
2. Create a branch which is some commits behind master branch and check it out.
3. Open a file from this repository in Creator.
4. Select "Tools" -> "Git" -> "Local Repository" -> "Branches..." from the menu.
5. In the Branches dialog, hover the mouse over the branch from step 2 and note the commit ID being shown.
6. Click on "Local Branches" -> "master" and click "Rebase".
7. After rebasing finished, hover the mouse over the branch from step 2 again.
   Creator will still show the same ID as in step 5.

The top commit's ID for a branch must change when rebasing the branch. The dialog should update to reflect this change.
