Menu locator filter: Fix that e.g. recent files were no longer available

Amends aed2c2c716
After checking which actions are enabled we may not trigger the menus'
aboutToShow anymore, since this can completely rebuild the menu
including recreating the actions. We also don't have to, since this
moved to before checking which actions are enabled.
