Email and Messenger bug

[Joseph H]

Hello, We are using Blesta 5.5.2 with PHP 7.4

We recently had an issue with our SMTP which caused for emails to fail, but Messenger succeeded to send and SMS. 

SMS sent

Issue is since Blesta was trying to resend the email it was also triggering SMS to be sent to the user causing a flood of SMS. every 5 minutes. Would be good to make it only retry the failed method individually.
