Synchronous, best-effort companion to getScrRefForProject: returns the already-computed
conversion into projectId's versification if one is cached, otherwise the raw stored reference.
Never fires a round-trip. Used for the initial displayed value and when detaching a web view so
callers never block on the async conversion. Returns the raw reference when no conversion is
needed (source frame unknown or already projectId) or when a conversion has not been computed
yet.
Parameters
scrollGroupId: undefined|number
Scroll group whose reference to read. If undefined, defaults to 0
projectId: string
Project into whose versification the reference should be converted
Returns SerializedVerseRef
The cached converted reference, or the raw reference when none is available
