Correctly close intro circuit when deleting ephemeral HS

When deleting an ephemeral HS, we were only iterating on circuit with an
OPEN state. However, it could be possible that an intro point circuit didn't
reached the open state yet.

This commit makes it that we close the circuit regardless of its state
except if it was already marked for close.

Fixes #18604
