IndexedDB: Clean up boilerplate when throwing TransactionInactiveError

IndexedDB: Clean up boilerplate when throwing TransactionInactiveError

Chrome's implementation provides different detailed error messages for
the various API methods to distinguish between the transaction being
merely inactive (between event dispatches) and finished (committed or
aborted). Reduce the boilerplate in each method by letting the
transaction introspect to provide the message.
