Title: Fixed an issue with mailers not inheriting directly from ActionMailer::Base

The inheritance verification failed when a mailer class didn't inherit directly from ActionMailer::Base

ex:

class GenericMailer < ActionMailer::Base
...
end

class UserMailer < GenericMailer
...
end

Mails would not get sent because of how the inheritance was checked.
