VisorSnapshotStatusTask returns empty result for restoring snapshot until snapshot check is completed

Currently, snapshot check is performed under the hood during restoring of a snapshot. For big snapshots check operation execution can take a long time.
In such case, if you call two similar commands, they will return different results:
Deprecated command restore --status shows, that snapshot operation is in progress:

Command [SNAPSHOT] started
Arguments: --snapshot restore test_snapshot --status 
--------------------------------------------------------------------------------
Command deprecated. Use '--snapshot status' instead.
Snapshot cache group restore operation is running [snapshot=test_snapshot]
Command [SNAPSHOT] finished with code: 0

But actual command --snapshot status does not show that any snapshot operation is running:

Command [SNAPSHOT] started
Arguments: --snapshot status 
--------------------------------------------------------------------------------
There is no create or restore snapshot operation in progress.
Command [SNAPSHOT] finished with code: 0

VisorSnapshotStatusTask.java rely on snapshot restore metrics[1]. This metrics are extracted from SnapshotRestoreProcess#lastOpCtx [2], which is updated in SnapshotRestoreProcess#prepare [3], but this method called after snapshot check is finished [4, 5].

Here is a reproducer: SnapshotStatusReproducerTest.patch
