[Persistence] Avoid redundant calls to persistenceService

Browse Source 
Mutation now triggers persistence; this means that some legacy code
does or may issue redundant calls to persistence after mutating.
To avoid issuing redundant calls all the way down to the
persistenceService, bail out of persist calls early if there are
no unsaved changes to persist.
