JAMES-2182 IMAP processors should catch InsufficientRightsException

Otherwise, that exception won't be caught and result in this error log:
```
 [ERROR] o.a.j.i.p.AbstractMailboxProcessor - Unexpected error during IMAP processing
org.apache.james.mailbox.exception.InsufficientRightsException: user '[email protected]' is not allowed to delete the mailbox '#private:[email protected]:sharedMailbox.child1'
```
While it is a client side error.
