Visual Bug when adding users to a calendar / searchbar results

[ZID-TU-Graz-Collab]

Steps to reproduce

1. Create a new calendar
2. Edit the calendar to add a person to that calendar / share that calendar
3. Look up a name that exists multiple times, the first few hits of a bigger result list can not be seen, neither can you scroll up further to see them.

Expected behavior

The results can be scrolled up all the way up to the top results

Actual behaviour

When having a result-list of multiple testuser (from testuser 1 up to testuser 15, etc.) the first results can not be seen, as you can not scroll up all the way to the top hits.
This behaviour was testet with multiple names, to save excessive workload creating testaccount. Thus, the screenshots refer to the last name „Müller“. As seen, results above Müller, E (alphabetical) will not be shown, except looking for them specifically

This must be new with #4515. The <SharingSearch> component uses the deprecated NcMultiselect component. The z-index of the multiselect must be incorrect. We can either fix the z-index (quick fix) or replace NcMultiselect with NcSelect.
