lib: rewind BEFORE request instead of AFTER previous
This makes a big difference for cases when the rewind is not actually
necessary to perofm (for example HTTP response code 301 converts to GET)
and therefore the rewind can be avoided. In particular for situations
when that rewind fails, for example when reading from a pipe or similar.
