fix(zoho-desk): enrich prevState with contentText symmetrically with payload

formatInput derived plain-text contentText only on payload, so an update event
for a comment/thread left prevState as raw HTML while payload carried
contentText - inconsistent shapes for before/after comparisons. Apply
withDerivedContentText to prevState too. Test asserts both are enriched.
