Fix various issues with Addsan server tests
The major fix here was to close a memory leak in XMLSchemaValidation.cc.
There were also some issues with how sqlite was being used. (You can't bind a return-by-value vector1 into a query - the temporary vector gets deleted before the query actually gets run, resulting in an memory access issue.)
These fixes now turn the integration.addsan test green on the test server. The unit.addsan still has issues with the crashing DynamicAggregateFunctionTests, and differential results with AntibodyTaskOps tests
