Subject: [PATCH] Fix duplicate label selection bug in
 AutocompleteLabelSelector

When attempting to create a label that already exists, the component
would add it to the selected labels without checking if it was already
selected, causing duplicate entries.

Now checks if the label is already selected before adding it.

Fixes issue where creating labels via label select allows duplicate
labels if the label is already assigned.
