Title: Initialize HMC variables in mcmc_writer_test

@bgoodri noticed that the mcmc_writer_test was failing but not picked up by Jenkins. The problem is that uninitialized variables were assumed to be zero, and with recent changes to ps_point explicit initialization was removed. The default values are undefined and hence machine-dependent. The test now explicitly initializes the variables before testing the mcmc_writer I/O.
