Bugfix Github bot: the right urls are now compared

The Github was comparing the wrong urls, which would make the bot
think that a job offer that's already been committed wasn't, and
thus committing it again, causing endless cycles of committing the
same job offers.
This fix should prevent this bug to occur.
