No push notification sent when an invite is withdrawn

[eyecreate]

Description

When a user asks to be notified of member events, they are notified when invited etc, but if their invite is rescinded, they are not notified, despite the info being available from a call to /sync. (Can see member event rescinding the invitation from room now left)

Steps to reproduce

• Have user ask to be notified of member events(https://matrix.org/docs/spec/client_server/latest#m-rule-member-event with action as notify)
• Have another user invite to a room and they afterwards rescind invite. (invite->leave)
• User gets notified of invite but not invitation rescinded.

Version information

• synapse:1.4.1
