  1. Refactor _run and rename to _result 

    Move all common code out of _run for HamiltonianPhaseEstimation and
PhaseEstimation, and rename _run to _result, because it only
creates the result class.

  1. Add cutoff to filter in test_from_bound 

    * An unknown change in the past three weeks caused tests to fail
with the default filter threshold of 0 (no filtering). I added
a small cutoff so that the tests pass again.

* Fix linter complaints
