Currently there is a possibility for modifying operations to fail because of I/O errors and a new tree to be created on another shard. This commit adds existence check for modifying operations. Read operations remain as they are, not to slow things. `TreeDrop` is an exception, because this is a tree removal and trying multiple shards is not an unwanted behaviour.
