command/read: run in main thread 

The read command calls store.Flag in a separate goroutine unnecessarily.
Calling this method on store should be very fast, as it only sends a
message to the backend worker and does not wait on IO.

Call the store.Flag method from the main thread. Remove wrapper function
and call store.Flag directly for cleaner code.
