processFilter not prepending ga: across all filter expressions

[GoogleCodeExporter]

Given a filter string of"

customVarValue1=~^/(tip|story)/[0-9]+;customVarValue2==1

I expect this (before URL encoding):

ga:pagePath=~^/(tip|story)/[0-9]+\;ga:customVarValue2==1

I get this instead:

ga:pagePath=~^/(tip|story)/[0-9]+\;customVarValue2==1

If I change my filter string to include "ga:" before "customVarValue2" the 
filter looks correct, but I still get no results. However, I do get results 
using the same filter (and other) parameters in the Google Analytics Query 
Explorer.

Note that customVarvalue1 should be pagePath in the first string.
