When running the QA, we copy the rapi certficate to the
machine which steers the QA to use it later in the QA
for testing RAPI calls. However, before we get to that
part of the QA, the rapi certificate is replaced when
'gnt-renew crypto' is called.

This patch makes sure that the new rapi certificate is
copied to the steering machine so that later RAPI calls
do not fail. It remains mysterious how this worked before.
