pull request merged / closed webhook contains empty body

[jpraet]

The body is empty in the webhook payload for pull request merged / closed events.

This is causing a problem with the redmine_merge_request_links plugin: tf/redmine_merge_request_links#27

At first I thought that this behavior maybe was intentional, but looking at the code, I don't think it is:

gitea/modules/notification/mail/mail.go

Line 127 in c61b460

pr.Issue.Content = ""

The pr.Issue.Content is emptied in the e-mail notification code, and as a side-effect the issue content is also empty for notifiers that are called afterwards (indexer, webhook and action).

Such unexpected manipulations of the notification input also happens here:

gitea/modules/notification/mail/mail.go

Line 57 in c61b460

issue.Content = ""

gitea/modules/notification/mail/mail.go

Line 154 in c61b460

comment.Content = ""
