Fix participant-create-wizard

[luisa-beerboom]

While trying to replicate #2787 (which I didn't manage to do at first) I instead found that the meeting-specific information form didn't appear for a meeting admin trying to add a user from another meeting.

I fixed that one.

Also fixes #2787

The meeting specific information is still missing.
Additional information:
the meeting specific information is only missing in the dev-environment
I could not reconstruct this behaviour in production-environment

to trigger #2787 you need an autoupdate.
e.g. be at the broken mask and then set yourself present or not present

It is fixed for me in firefox and chromium, what exactly are you doing?

Doesn't work for me. The personal information form flickers a bit, but there's no permanent enabling. Does this only happen in prod or smth?

Can't replicate this, unless X is also in another meeting. Please mention such things.

The form is no more editable but on every change of the present status the form fields flicker from disabled to enabled and back to disabled.

That is a pre-existing bug. It should not be considered as part of this PR. Please create a separate issue.
