Xavier Morel 4b12d88b3e [IMP] runbot_merge: remove unnecessary uniquifier dummy commits
"Uniquifier" commits were introduced to ensure branches of a staging
on which nothing had been staged would still be rebuilt properly.

This means technically the branches on which something had been
staged never *needed* a uniquifier, strictly speaking. And those lead
to extra building, because once the actually staged PRs get pushed
from staging to their final destination it's an unknown commit to the
runbot, which needs to rebuild it instead of being able to just use
the staging it already has.

Thus only add the uniquifier where it *might* be necessary:
technically the runbot should not manage this use case much better,
however there are still issues like an ancillary build working with
the same branch tip (e.g. the "current master") and sending a failure
result which would fail the entire staging. The uniquifier guards
against this issue.

Also update rebase semantics to always update the *commit date* of the
rebased commits: this ensures the tip commit is always "recent" in the
case of a rebase-ff (which is common as that's what single-commit PRs
do), as the runbot may skip commits it considers "old".

Also update some of the utility methods around repos / commits to be
simpler, and avoid assuming the result is JSON-decodable (sometimes it
is not).

Also update the handling of commit statuses using postgres' ON
CONFLICT and jsonb support, hopefully this improves (or even fixes)
the serialization errors. Should be compatible with 9.5 onwards which
is *ancient* at this point.

Fixes #509

Execute this test suite using pytest.

The default mode is to run tests locally using a mock github.com.

See the docstring of remote.py for instructions to run against github "actual"
(including remote-specific options) and the end of this file for a sample.

Shared properties running tests, regardless of the github implementation:

* test should be run from the root of the runbot repository providing the
  name of this module aka ``pytest runbot_merge`` or
  ``python -mpytest runbot_merge``
* a database name to use must be provided using ``--db``, the database should
  not exist beforehand
* the addons path must be specified using ``--addons-path``, both "runbot" and
  the standard addons (odoo/addons) must be provided explicitly

See pytest's documentation for other options, I would recommend ``-rXs``,
``-v`` and ``--showlocals``.

When running "remote" tests as they take a very long time (hours) ``-x``
(aka ``--maxfail=1``) and ``--ff`` (run previously failed first) is also
recommended unless e.g. you run the tests overnight.
