Register `mailer.message_logger_listener` only when profiler enabled to prevent memory leaks as suggested in:
- symfony/symfony#50580 (comment)
- symfony/symfony#50580 (comment)

~~`@stof` can you guide me about the way how to implement your second suggestion too? symfony/symfony#50580 (comment) UPD: resolved

_This change may be considered as a minor BC break - DI service won't be available anymore with disabled profiler._
