Normalized test name matches int and string indexed data provider

An simple attempt to fix #67

Tell me if I can improve something.

I tried to keep the regexes simple. It could be merged into one but the $matches array index handling would be harder depending on the case.

I just fixes phpcs on strtr. But as there is no test on BrowserExtension, I am not sure if I need to do something for the codecoverage alert.

Thanks for catching this edge case @flohw.

Don't worry about the code coverage - I only use it as a loose metric and this is a tough class to test.
