when patching a message, the allowed_mentions property is deleted

[arnimattr]

Description
When I patch a message, the allowed_mentions property is resetted/deleted if I don't send it in the body again. On the other hand, when I update only the content property, the components property doesn't change (as it should)

Steps to Reproduce

1. create a new message using
   POST /channels/{channel_id}/messages { "content": "test <@{user_id}>", "allowed_mentions": {"parse": [] }, "components": [] }
   --> the user should not be mentioned

2. update the message using
   PATCH /channels/[channel_id}/messages/{message_id} { "content": "now I mention <@{user_id}>" }
   --> the allowed_mentions property doesn't work anymore

• this only works if the message has components!

Expected Behavior
the allowed_mentions property should still work and the user shouldn't be mentioned

Current Behavior
the allowed_mentions property is deleted

The allowed_mentions property isn't stored. You have to send it every time content is created or updated. See #1864.
