Multiple Tests using Mock Plugin fail

For some reasons the tests in WebSecurityConfigTest that use the Mock plugin cause other tests in ServicesEndpoint (that also use the Mock plugin) to fail with a FileSystemNotFound error that comes from the Mock plugin.

It seems to be related to how the formsfeeder.core ResourceFactory loads files from the .jar path when running under Maven and SprngBootTest.

For now the offending tests are @Disabled, however it would be nice to correct the issue and then re-enable the tests. All tests run fine when run from Eclipse's JUnit runner. The problem only appears in the Maven build process.
