Description of Changes Made

This PR changes the behavior of isDataQuery flag, instead passing it as false by default on Prepare step, when query is parsed, and then passing the updated value only on Execute step. This avoids duplicated entries in query history for the same query with, for instance, Tablaeu, which would parse the query and get its meta result first, then repeat the same steps, but next time execute the query.
