Remove conflicting multiselect

[skjnldsv]

See #1831
@blizzz can you check the ldap please?

It should be using the other jQuery ui multiselect, this is the last location I could find where it was being used :)

Should this be in 15? Or better wait for 16?

[skjnldsv]

@MorrisJobke ideally 15. But if this is too complicated, i'll add a stricter css rule to backport it to 15 and make sure we ignore this conflict :)

I was able to complete the full setup and use the multiselect without any issues. The multiselect in core have nothing to do with the multiselect used in the ldap config
Let's review!

Checked with rg multiselect -g \!3rdparty -t js -M 150 and couldn't find any occurences of a multiselect apart from the Vue one.

I'm unsure if we should do this that late in the cycle. Also it looks like ldap is depending on this. It seems there is a second multiselect in LDAP. I tested it as well and it still works fine.

Works 👍

I'm unsure if we should do this that late in the cycle.

I would like to get some feedback from @juliushaertl@rullzer and @nickvergessen about this.

It seems to work. Let's do it to avoid weird patches.
