Steven Allen 2857f6c0ed fix: use a consistent tipset in commands
It's very easy to write an incorrect command that operates over
different heads by using the "empty" tipset. This change makes the
`LoadTipSet` command helper get the latest head from the lotus daemon if
its unset.

The cost is an extra call to get the head. That should be trivial in
most cases.
