Removed officer alert in admin section

[MariaCheca]

What

Removed alert appearing in admin section when an admin user also poll officer is in this section, as requested.

Made alert for poll officers just appear in the Officing section (http://localhost:3000/officing) instead all over admin section.

Test

As usual.

Deployment

As usual.

But... should that notice keep appearing for Officers? If so, where? I feel like there's something missing here... either:

• Totally remove the admin.officing_booth.title keys on both en and es admin.yml files
• Just remove the notice for the admins, but not for the officers (I suspect that app/views/layouts/admin.html.erb is being used underneath on the officing panel, thus the confusion thinking that there was a second place that was appearing/being rendered)

That's better! :) Most importantly... you've checked it works right? ^_^
