Fix "data object" tests

"data object" is postponed till 1.9

Related commit in kotlin repo:
https://github.com/JetBrains/kotlin/commit/f643cdf90b5c4af9d6988b6167957c9b76f02647

Use `// COMPILER_ARGUMENTS: -XXLanguage:+DataObjects` instead of
`// LANGUAGE_VERSION: 1.8` because it's more reliable and less invasive
