Ariadne Conill 88d064d80e http signature plug: remove redundant checks handled by HTTPSignatures library
the redundant checks assumed a POST request, which will not work for signed GETs.
this check was originally needed because the HTTPSignatures adapter assumed that
the requests were also POST requests.  but now, the adapter has been corrected.
