Add full inference test and remove mutation model ignore_ualabel call

[willdumm]

Fixes incomplete refactor in #91 after upgrade to historydag v1, and adds a test that runs inference with all criteria via the cli.

Inspired by:

number of trees with integer branch lengths: 396
  Isotype parsimony will be used as a ranking criterion
  Mutation model parsimony will be used as a ranking criterion
