- Print only warning instead of error, as the module is only optional
- Log the error to the debug log, so users dont think we didnt catch the exception

The oob tag is only added when a body tag exists with the same content. (means not unencrypted)
If any encryption plugin is active, there should be no cleartext body.
So no oob tag is added to encrypted messages.

This patch exists only for the OTR plugin.

This will only be added on not encrypted Messages

This happend due to copy/paste from httpupload
