[Qt-creator] corrected the v2.8.0-rc tag in git

[Ziller Eike]

Hi,
if you pulled the v2.8.0-rc tag directly from the repository, or wondered why it didn't just turn up when pulling from gerrit:
I accidentally tagged a local commit that, though it corresponds to a commit in the 2.8 branch, is not part of the 2.8 branch itself.
We have just corrected that (thanks Ossi), so might want to pull again.

Br, Eike
