Improper UI update after deletion of labels

[2knal]

Describe the bug
Deleting a label from Project labels page, deletes only the last label from the entire label list (UI bug; Label is deleted properly from the DB). After refreshing it, we can observe that the actual label which was selected having been deleted.
In a nutshell, one can observe that the last element gets removed from the UI, irrespective of deleting any of the labels.

1. Go to Project Labels option in the sidebar
2. Click on it
3. Create multiple labels
4. Try deleting any label, except the last one
