Addressing ATEAM-666: Although the bug reported there was due to malformed options, the IOVDbSvc did not catch the error and the folder markup parser entered an infinite loop allocating more and more memory until the job crashed. This fix traps the malformed markup in the IOVDbSvcParser and introduces a unit test to test the new behaviour. In addition, the BOOST-based unit tests are standalone, so the redundant output comparison files were deleted for these tests.
