Print SQL statement in error logs

[jeyhun]

Started including SQL statement in errors returned by DataStore, if the error was because SQL statement failed to execute

Sample error returned by Insert method:

SQL statement could not be executed [dbName=testcrudwithmismatchingorgid, SqlStmt=INSERT INTO "application" ("application_id","name","org_id") VALUES ('id-8674665223082153551','New app','')]
	ERROR: new row violates row-level security policy for table "application" (SQLSTATE 42501)

Let's not dump full stmt inside error, it could have unwanted consequences with security in callers. I prefer debug/trace log instead in a module.
