Queries should be able to be added onto an encrypted URL

[markwhiting]

If a query is added manually after an encrypted url it should still work fine. However, if the encrypted url already has queries, and the added queries mention the same variable, Surveyor should use the encrypted version.

So, a url like:
/e/asdlfjasdf/?WorkerId=Mark
Would work and pass WorkerId on to Surveyor.

However, if a url like:
/s/?URL=google.com& WorkerId =Mark was encrypted to /e/123abc, then /e/123abc/?WorkerId=Duncan&Day=Tuesday then Surveyor would get {WorkerId: "Mark", Day: "Tuesday"} and we would just ignore the repeated WorkerId value.
