Add whenever gem

I basically copied what was done here:
https://gitlab.coditdev.net/decidim/decidim-codit-demo-app/commit/e58a2e63c471f616f4c05065cb56b7619cd72577

Although in here the application.rb file isn't modified:
CodiTramuntana/decidim-barcelona_energia-app@dd755ae

Well done! Are you going to add the tests you've found that can be performed against Whenever schedules?

[tramuntanal]

@MarcReniu @isaacmg410, @aitorlb have probably found a bug because the active_job backend isn't configured to delayed_job in barcelona energia and probably some other installation.
Can you check please?

@tramuntanal I added the whenever-test gem and a spec, but dont know if it's that much help.
Just so you know, the schedule.jobs[:rake] used in the test returns the following:

[{:task=>"decidim:metrics:all", :every=>[1 day, {:at=>"2:00 am"}], :command=>"cd :path && :environment_variable=:environment :bundle_command rake :task --silent :output"}]

[MarcReniu]

Why adding whenever-test gem and a spec for rake tasks? I mean, metrics rake task has been already tested in decidim.

You're right @MarcReniu , that's why I said that I didnt know if it was of much help...
Should I revert back to the initial commit @tramuntanal ?

Great!
