NcSelect: User select - no Email addresses possible

[dartcafe]

Currently (v8.7.0) it is no more possible to select email addresses as shareees using NcSelect

Ref: nextcloud/polls#3335

Additionally the description line of the user object also vanished, which hides the actual filter match, if the search tern is found in another attribute than the name.

See #4491 as camparism, where the selection was possible and the desciption line was still present.

If I take a quick screenshot, I can see the options list with the correct item:

x	user @ foo.com	peter @ foo.com
netlify
Polls example

[dartcafe]

OK. I got further with it, since it seems description is now subName. But still the filter is broken.

Prior the property description was used as a description line and coverd by the filter (as far as I remember). Not sure, if the change was introduced here or prior to this. Currently neither the description nor the subName is displayed any more which was useful, if the search term does not match the displayName, but another property of the user.

This was a valuable feedback to the user. But now it seems not only be missing, it avoids correct filtering.

Not sure, if my conclusions are right. Please correct me.
