message_edit: Check previous message content to prevent races.

Browse Source 
Similar to group based setting values, we expect
the client to send the previous content alongwith
the edited content to the edit message endpoint.
We reject the request incase the previous content
doesn't match the current message content, which
could happen in case two users simultaneously edit
a message - which will be implemented in #33051.
