Removing unnecessary schema dependency from delegate unit tests.

* All of the unit tests were including the TfL schema even though it
is not used. This prevented building with delegate and not TfL parser.
* Fixing some template compile errors that were introduced when
FileComparisonExecutorTests.cpp was compiled without TfL parser.
