fix issue where multi-line dataproviders in phpunit were parsed incorrectly when displaying results

Summary: Found an issue where if arc unit runs phpunit and the datasets included a dataprovider which spanned multiple lines, it wasn't filtered out correctly in the result parser, this fixes it

Test Plan: accidentally ran tests against phpunit itself which exhibits this problem. no longer a problem after this fix, nothing else breaks.
