Fix compileJavaAgainstKotlin tests

- Use another API to get file name out of a javac diagnostic
  (.getSource().getName()'s behavior changed in JDK 8)
- Delete .txt files for those tests which check that javac reported a
  compilation error; the order and content of declarations in those
  files is undefined
