[PATCH] send-email: move process_address_list earlier to avoid, uninitialized address error

[Michael Strawbridge <michael.strawbridge@xxxxxxx>]

Move processing of email address lists before the sendemail-validate
hook code.  This fixes email address validation errors when the optional
perl module Email::Valid is installed and multiple addresses are passed
in on a single to/cc argument like --to=foo@xxxxxxxxxxx,bar@xxxxxxxxxxx.
