While we already had "one test to rule all stats", testing each method
individually makes reading, adding and changing tests easier.
Note we need to make all methods being tested public. We could also test
them using methods like `stats.generate[:total_valid_votes]` instead of
`stats.total_valid_votes`, but then the tests would be more difficult to
read.
Some queries were accessing original column instead of the new
translatable one. This should have been causing unexpected behavior
for requests maded in a different locale than the application default.
This way we can easily add a test which will fail if by accident we
change the method to use `Date.today`. Until now using `Date.today`
would only fail if we ran specs in a time zone with a different date.
Show a flash message that it's not possible to delete booth shifts
when they have associated recounts or partial results. Before an
execption was raised.
Make sure we create the Poll::OfficerAssignments in the same order the
booth_assignments where previously created. So the spec "Poll::Shift
officer_assignments creates and destroy corresponding
officer_assignments does" not fail.
This way we guarantee there will be at least one translation for a model
and we keep compatibility with the rest of the application, which
ideally isn't aware of globalize.
We needed to bring back support for CKEditor in our translatable form,
which we had temporarily remove.
And now we support CKEditor in our translatable specs, and so we can
remove the duplicated specs for poll question answers.
We need to replace ".title=" by ".title_#{locale}=" in one place because
for some reason globalize builds a new translation record when using the
latter but it doesn't build one when using the former.
