Fix for #1414: do not produce a compiler bug report when we hve typecehcker or java errors

errors that stem from ceylon code that doesn't typecehck are not bugs in the compiler,
because we reported errors for them and that's enough.
it's only a bug if we did not produce any error for ceylon or java source and we had
codegen errors
CeylonLog #1414: for some reason the error counting treated java errors in ceylon code as nonCeylon errors

And I suppose nonCeylon is only for java code
