There is no reason to insert the protocol filters in the insert_filters

phase.  This moves us to inserting the filters in the create_request
phase.  This makes more sense, because now the protocol filters are attached
to the request as soon as possible.  Previously, some requests never
called the insert_filters phase, so they don't get the filters.  Think
redirects for reqeusts that never call insert_filters.
