imapsieve: setting imapsieve_url disables admin scripts

[Gedalya]

Hello,

The documentation says imapsieve_url "has no effect on the administrator-controlled Sieve scripts". However, when setting this item, I get lines such as:

Error: imapsieve: mailbox INBOX: Failed to read /shared/imapsieve/script mailbox attribute: Mailbox attributes not enabled

and that's it. imapsieve_mailboxXXX_* settings are completely ignored. Unsetting imapsieve_url makes it all work again.
