change reaction api to match other interactions

Status reactions had an API similar to that of
announcement reactions, using PUT and DELETE at a
single endpoint.  I believe that for statuses, it
makes more sense to follow the convention of the
other interactions and use separate POST endpoints
for create and destroy respectively.
