Because of our partial loading implementation we need to specify
finishedAt and startedAt differently than we would normally do. For some
reason duration was not recalculated while loading record and specifying
raw attributes helps here.
* duration was not actually defined in Travis.Job, which may have caused
bugs when combined with partial record loading (so for example it was
ok on a refresh, but may have been broken on update)
* notStarted was not a dependency of duration
We no longer need this check, because it was only relevant with Ember
Data. Additionally it was a cause of a travis-ci/travis-ci#1992, because
of wrong syntax:
unless someFunction false or true
will only check for a result of someFunction with an argument being the
result of `or` expression.
