[fgenubeo]

Module

mail_composer_cc_bcc

Describe the bug

The method '_generate_template_recipients' in model 'mail.template' (models/mail_template.py) set a local variable res_id_to_company at the wrong position. Because it assign them in a if and we use it in other block of code.
So it raise this error :
File "/mnt/OCA-social/mail_composer_cc_bcc/models/mail_template.py", line 126, in _generate_template_recipients
record_company = res_id_to_company.get(res_id)
UnboundLocalError: local variable 'res_id_to_company' referenced before assignment

To Reproduce

17.0:

Steps to reproduce the behavior:

1. Just send an email where variable 'find_or_create_partners' = False

Expected behavior
Normaly, we are able to send email without error
