The tests check that expected errors actually happen.
There might be *too many* error markers in the tests,
since it's not clear *where* an error is reported.
Is a naming conflict reported for one or both conflicting declarations?
Is a conflict reported on the class declaration or on a conflicting
declaration?
The front-ends might need to remove themselves from some of the errors,
when the error reporting strategy is decided, but they should report
at least *one* error for each problem.
Also fixed bugs in the non-error `enhanced_enum_basic_test.dart` file.
