api: Upon bucket delete remove in-memory state properly. (#4716)

Browse Source 
This PR fixes the issue of cleaning up in-memory state
properly. Without this PR we can lead to security
situations where new bucket would inherit wrong
permissions on bucket and expose objects erroneously.

Fixes #4714
