stray end function in class causes errors to not be reported

in this file with the extra end function towards, the end, there was no compile error reported - the output was garbled, and the compiler on the box failed.

Start by reducing the supplied BrightScript snippet to a parser or compiler test that includes the stray end function inside the class. Trace how the compiler handles the unmatched terminator and verify that compilation reports an error instead of producing garbled output or failing without a diagnostic.
