multi-domain rerun broken - Redmine #2105

Some refactoring that converted !bNotLastFrame to bLastStep in commit:3da127 that was attempting to simplify do_md omitted to consider the logic in rerun_parallel_comm. This could lead to segfaults or infinite loops for reruns with more than one domain.

This case should have been covered by mdrun-test -nt 2 (or the newer mdrun-test -ntmpi 2 on master), which apparently has not been running in Jenkins for more than a year.
