Dmitrii Stepanov 71fac2b9c3 [#661] shard: Fix Delete method
Due to the flushing data from the writecache to the storage
and simultaneous deletion, a partial deletion situation is possible.
So as a solution, deletion is allowed only when the object is in storage,
because object will be deleted from writecache by flush goroutine.
