tdf52391 don't accept format-only changes secretly

for Reject all in Manage changes dialog window.
Now clicking on Reject all keeps format-only changes
instead of accepting them during the requested rejection
to allow to check them before acception.

Note: LibreOffice cannot reject the format-only changes.
If changes are all format-only changes, the Manage
changes dialog hides the Reject all button, also the
Reject button for the selected format-only changes.
This patch extends this workaround to avoid unintended
acceptance of rejected changes.
