Changes: Remove QRegion comparision before assignment
Changes: Remove QRegion comparision before assignment

RevBy: Jarno Malmari
Details: The code in MIMPluginManager::updateRegion() does not rely on the
comparision, therefore it was removed. It should be noted though that - due to
the normalization of QRegions - such comparisions tend to be fairly efficient.
