Translations

Fixed problem with devise links translations. I moved them to the general translation file (es.yml) as not even devise is considering this in their i18n package sets. Then used full path e.g t("devise.shared.links.sign_up")

I have also added translation for "Entrar" and "Recordarme" in the login page

In this PR I am also adding a fix to inquiries rspec controllers, so all existing Rspec tests can pass (inquiries was missing association with organization)
