Although the original idea with structured logging was that the test ids could be tuples, it turns out that downstream consumers often don't work well with a string|tuple datatype e.g. it doesn't work well with a database. So we should stick to using pure-string identifiers.

The idea of mozlog ids being tuples unfortunately didn't work so well with external systems that found the tuple|string datatype difficult to work with. Convert reftests to use simple ids of the form "<test url> <comparison> <refurl>" e.g. "about:blank == data:text/html," instead of tuples.
