Purpose

Nice to have for:

• When a collection gets enabled you would usually always want to sync it right away too.
• Force-read-only setting: gets set/updated at sync only (see "Force read-only" setting not effective immediately #851).

Short description

• Pass account of the changed collection along when notifying listeners of collections change.
• Then have SyncWorkerManager listen to any collection changes and use the account passed along to trigger a one time sync of the whole account (not just the service which the collection belongs to - although that would prob be possible as well).

Checklist

• The PR has a proper title, description and label.
• I have self-reviewed the PR.
• I have added documentation to complex functions and functions that can be used by other modules.
• I have added reasonable tests or consciously decided to not add tests.
