[TEST] Fixed the incorrect indentation for the `skip` clauses in the REST tests

This patch fixes the incorrect indentation in the REST tests, which makes tests in language runners (eg. Ruby, Python) to fail, since the skip clause is parsed as an empty value. Tha Java YAML parser is smarter/lenient about whitespace, so it doesn't catch this.
