Fix: Check whether header value contains msgidHEADmaster

This is better because of the "References:" header field. The field may
contain several entries.
As the `mailparse` library does not return a `Vec<>` of values here, we
simlpy use the `String::contains()` function to check whether the mails
could be related.
