Label named "No Label" can't be searched for
- create label "No Label"
- create issue "without label", assign no label
- create issue "with label", assign label "No Label"
- search for issues with label "No label" via clicking on label in label view
- issue "with label" should show up, but issue "without label" shows, due to the "show unlabeled issues" filter using the magic name of "No Label".
Resolution: either don't use magic value or detect creation of ticket with magic value as name and forbid.
Note: searching for "labeled with any label" works fine due to label names not being allowed to be empty on creation.
