Moved FilterInterceptor to CSpace and updated FilterQueryVisitor to get metadata from CSpace. This will allow Filter to work where model has mapping to a different schema in database.
Added model with norwegian names and mapping to same database and unit test to verify filter works with mapped model
Added extra check for PropertyInfo on Dataannotations property may be null
