The call to `except` here should not be an array as there is no array of these symbol to exclude from the hash. This issue was kindly identified by @inulty-dfe in #162.
With a view mail we have to call `mail` twice, once to get the body of the email from the view and once again to override the format contents. We were passing in any custom headers for both calls which was resulting in duplicate headers in the message. By calling `mail` without the headers, we can get the body and not modify the headers, leaving that for the second call. Interestingly adding custom headers is pointless, as they will never end up in the email from Notify - we may want to stop messing with the headers at all - I think it is a hangover from the v1 implementation. This was kindly identified by @inulty-dfe in #162 who are testing the header Mail::Fields that are potentially duplicated.

This work sets out to resolve the two issues reported in #162 by @inulty-dfe.
We fix the first issue on the call to
Hash.except.We then stop the potential for duplicate headers ending up in the Mail::Message, by only sending the headers once to
mailinview_mail.This work will form the basis of v2.0.1
