Make bananas deletable

Closes #592 (closed)

What does this MR do?

Bananas can be removed by a button next to them in the banana list. For now, it is only possible to remove bananas that you received on your own profile, but we can change the permissions if needed.

I added some bananas to the seed data for testing.

How confident are you it won't break things if deployed?

I can't think of anything that would break here. It should work.

How to test

Steps a reviewer can take to verify that this MR does what it says it does e.g.

1. Checkout branch locally
2. Run ./scripts/seed to add some bananas
3. Login as foodsaver
4. Go to your profile page
5. Open the banana list
6. Click the delete button (trash bin) next to an entry and confirm in the next dialog
7. Reload the page and check that the banana is gone
