Artem Bilan 56474a5ef5 GH-3560 Parse mail FROM as comma-delimited header (#3562) ...

Fixes https://github.com/spring-projects/spring-integration/issues/3560

According RFC 5322 `FROM` and `REPLY-TO` received mail message can be
as an array of addresses.

* Fix `MailUtils` to present those arrays as comma-delimited strings for
Spring message headers
* Fix tests to deal already with several addresses for `FROM` mime header.

In the future we may change the logic to map those mime headers to arrays
as it states according the mentioned RFC

**Cherry-pick to `5.4.x` & `5.3.x`**
