There were some roscpp changes that are exposing gaps in test coverage,
especially wrt command-line tools.

The specific change is that ros::Time::now() now throws an exception if it's
used before roscpp knows if simulated time is in use (to do so it needs to
contact the master and check the /use_sim_time parameter).  This makes what
were difficult to track down bugs (caused by Time::now() initially returning
wall time and then jumping to simulation time) into easy ones, but has
broken some things in the process.
