conflict with Nextcloud Office aktivated

[AStroppy]

If both addons 'Office Online Integration 2.1.0/2.1.2' and 'Nextcloud Office', Nextcloud Office doesn't work anymore. Also, in Office Online Integration it isn't possible to edit documents even it's a new document. Nextcloud Office can't open documents and it is shown a blank screen.

Users get the correct Office to use by group membership (Collabora or MSOffice).

I'm still on 'Nextcloud Server 27.1.8' and 'Office Online Integration 2.0.3' because everything works fine there.

For me the newer versions since 2.0.3 don't work as expected.
