Unable to leave team

When
- creating a team
- adding somebody else as admin

I'm unable to leave that team -- in "Members", the "Remove" button for myself is greyed out.

I managed to work around this for now by removing the `disabled` state from that button using the browser's devtools.

No file or test is named in the issue. Reproduce the flow by creating a team, adding another admin, and checking the Members view; the fix is done when the creator can leave the team without changing the button through browser devtools.
