Ignore calendar emails when getting the style of the conversation #2
Description
Calender mails are irrelevant for the purpose of getting "the style" of a former conversation and should be left out for that reason.
For reference, this is what a calendar Mail source looks like

We can filter out all mails which contain a text/calendar block, however, this might create some false-positives when you actually answer to an invite, a risk I'm willing to accept. The whole "respond in the same style" feature is not relying on every mail there is.
