ItTablesApiTest#testTableAlreadyCreatedFromLaggedNode is flaky

No link here, failure can be reproduced locally.

Here's the flow of events:

• MetaStorageManager#storeEntries starts its execution, revision is equal to 2, for example;
• At the same time, MetaStorageManager#updateAggregatedWatch is called by the inhibitor in the test;
• "storeEntries" reads an applied revision value, it's 1.
• "updateAggregatedWatch" reads an applied revision value, it's still 1.
• New watch is started, using revision 2 as a base.
• "storeEntries" writes data into the vault, applied revision becomes 2.
• New event from new watch appears:
  • revision of the event is 2, because that's the base;
  • revision read from Vault is also 2;
  • we get an exception that these two cannot be equal.
