Revert "Fixed key sequence eating behavior for QShortcut and QAction."

This reverts commit 031adeaf42ddaef8d01338f6c59ba97170be5d53.
The patch had some unforeseen side-effects for Creator.
It may also affect other existing applications in a similar way.
For now, this behavior (eating key sequences for disabled shortcuts)
should be achieved using a local workaround in creator.
