Description

When client started only subset of all cluster caches, it can have issues on reconnect.

If cache isn't started on client, it still registered some SQL structures:
GridQueryProcessor#initQueryStructuresForNotStartedCache

but these structures are not cleared on disconnect:
GridCacheProcessor#onReconnected

This leads to exception on reconnect:
