Ensure "Quick annotations" action is always disabled on protected pdf

If the annotations are disabled in the current pdf we can skip repopulating "Quick annotations" and in this way we also assure that the enabled/disabled state of the action is preserved upon configuration reparsing.

d->toolsEnabled must be initialized to true, in order to correctly populate the "Quick annotations" action the first time for non-protected pdf, given that setToolsEnabled is called after the first call to populateQuickAnnotations.
