Nicholas Hurley 4eb476eee2 Bug 1390274 - only parse URIs in the predictor when absolutely necessary. r=valentin
This moves URI creation from ParseMetaDataEntry into SetupPrediction
because ParseMetaDataEntry is called in way more circumstances than we
actually need the URI from. Even in those cases where we might use the
URI (but it's not guaranteed), we end up using the URI less often than
we create one. In case it wasn't clear, SetupPrediction is the only
thing called post-ParseMetaDataEntry that would require a parsed URI in
the first place.

SetupPrediction has the duplicated NS_NewURI calls to avoid creating
URIs for those calls to SetupPrediction that are no-ops.
