Fix class run configuration applicability (KT-33787)

The bug appeared when we turned “ultra light classes” on by default.
  The difference with the old implementation is that
  PsiClass.getTextRange() returns the correct non-null value.
  This triggers JavaExecutionUtil#stepIntoSingleClass() to return
  a light class instead of the original location (of a PsiIdentifier).
  So AbstractJavaTestConfigurationProducer#isConfigurationFromContext()
  returns true, and the wrong configuration is reused instead of
  creating the new one.

By the way, for Java it also returns an identifier because of the
  PsiTreeUtil.getParentOfType(element, PsiClass.class) != null check.

The proper fix should land in the newer versions of IDEA, however this
  (hopefully, temporary) hack will fix test method gutters for
  all platform versions.
