`mail()` without arguments is a getter for the current mail.
This behavior is documented in our guides (http://edgeguides.rubyonrails.org/action_mailer_basics.html#action-mailer-callbacks)
but was broken in the past. This commit short curcuits
the `mail` method if:
1. mail() was previously called
2. no headers are passed
3. no block is passed
Closes #13090.
