Filter query parameter before decidePolicyForNavigationAction

Reviewed by Wenson Hsieh.
Currently, query parameters are filtered from a cross-site navigational URL
relatively early in the load process. However, there is an edge case where this
fails when
1) we only filter parameters based on the source web page, and
2) we handle a redirect that results in a process-swap
When we have this case, then the current document's URL doesn't reflect the
actual source document's URL (after PSON). I could solve this by plumbing the
originator/initiator, but instead I decided to filter the request URL before we
potentially PSON.
