Publishing room to homeserver room directory should not require m.room.canonical_alias permission

[CromFr]

Description

On current riot.im/app (1.6.2), not having the m.room.canonical_alias room permission disables all controls in Room settings -> Room Addresses, including the Publish this room to the public in tcharles.fr's room directory? switch.
I don't think this is expected behaviour as the permission for this feature is set in Synapse config (room_list_publication_rules), and querying directly the endpoint using curl (PUT on _matrix/client/r0/directory/list/room/:roomID) is still allowed without having the m.room.canonical_alias permission.

Steps to reproduce

• Using a default synapse instance (or matrix.org)
• Create an empty room
• Demote yourself to Default or invite a new user
• Open Room settings -> Room Addresses, the publish button is disabled and can't be toggled.

Note that Element Android doesn't have this restriction (v1.0.13 at the time of writing, but possibly older versions as well).
