Comment:

 In [changeset:"8358" 8358]:
 {{{#!CommitTicketReference repository="" revision="8358"
 Harden GenericRdbms core against non-existent geom properties or non-
 existent class names.

 Various *FilterProcessor subclasses blindly assumed a referenced geom prop
 or class name cannot possibly be invalid and will always exist when we ask
 for it. This is a recipe for nullptr deref that will segfault/crash the
 calling FDO client application.

 Added test suite (inherited by all GenericRdbms providers) that exercises
 queries with non-existent geom props and class names. Before this fix was
 in place, these test runners crashed out, confirming the issue. With the
 fix in place, these test runners now run to completion.

 Fixes #1011
