Move ModulePreferences to Profile.userInfo (#993)
Store module preferences in the Profile.userInfo field for atomicity.
Access and modification are dramatically simplified, and synchronization
comes for free.

On the other side, fix provider preferences synchronization by using
viewContext for the CloudKit container.

Fixes #992
