Test helper was incorrectly returning failure body

The _process_unauthenticated method in test_helper was returning
the response as the body. When setting rendering the text, it was
calling to_s on the response which would render something like
this: #<ActionDispatch::Response:0x007fb9e1efea00>. This change
renders the body of the response instead of the response itself
Use "number of" instead of "amount of" for countable nouns.
Update CONTRIBUTING.md
Missing https:// in Google Group link
Assigns object to self.resource, changing variable scope.
Separates sign_up and sign_in on Registration

See #2104

Completed with the help of @rubynortheast
Moves sign_up from helpers to controller
Make #set_flash_message respect i18n-set resource_name

Using #devise_i18n_options allows overriding any i18n keys but the
resulting call to I18n.t does not respect an override of resource_name.
Add test for #devise_i18n_options allowing resource_name override
Add failing test for Issue #1994

Lockable should not leak information about account existence if paranoid
mode is on.
Unit test for Lockable#unauthenticated_message not leaking account existence

This is another failing test for #1994, a unit test for Lockable. Lockable's
#uanauthenticated_message should not return :locked if paranoid mode is on
and instead should return the generic :invalid response.
Fix #1994 Lockable no longer leaks account existence
