Log in on Island restart bug

[shreyamalviya]

Describe the bug

If you run the Island, stop it, and run it again within a few seconds (I don't know the exact time for which this happens), you don't have to log in to the Island again, and you get an error in the credentials repository (because without logging in again, the encryptor can't be unlocked).

It goes away if you logout (using the /logout endpoint) and then login again, and any credentials configured will also appear in the configuration then.

To Reproduce

Steps to reproduce the behavior:

1. Run the Island
2. Configure some credentials
3. Stop the Island
4. Run the Island again
5. Check Island logs for error
6. Check configured credentials to see none
7. Use the /logout endpoint to log out
8. Log in again
9. Check Island logs for no errors
10. Check configured credentials, you can see them again

Expected behavior

You should be asked to log in again if the Island is restarted. The credentials repository error will also go away then.
