Title: Handle invalid dependent job (missing parent(s)) on load

Allow safe loads from bad persisted state.

In particular, if some dependent job's parents no longer exist,
Chronos will die when elected as master.

This pull request allows Chronos to gracefully detect and remove
dependent jobs that can no longer be honored.
