RFR: 997: Email notifications are not sent to alias if binary change is commented in Gitlab [v2]

[Erik Joelsson]

> This fixes an NPE when parsing a review comment from Gitlab on a binary file. Such a comment does not have a line, and I picked the value 0 to signal that. I also updated the email formatting of such comments to skip showing line numbers and quotes from the file.
