Fix selfie with invalid data in some circumstances

Browse source 
Reported internally.

The issue involves `removeparam` filters with a regex value. When
such filter was visited before a selfie was created, this would cause
the created selfie to persist a RegExp object, which can't be
serialized. This would cause exceptions to be thrown when uBO would
be subsequently loaded with the tainted selfie, since uBO would try
to execute a plain Object as a RegExp.
