Error: /api/sync returned disallowed changes -- declining an invitation

[sentry-io]

Observed behavior

Seems declining a channel invitation results in the change being disallowed. I do not believe this is a regression. See the attachment in the Sentry issue for the change objects. Here's a preview:

[

{
"channel_id": "a28114cfd97a4def9b0910334ec3fcff",
"key": "4d6f8f3aeef045408e19a1a4114dbfa9",

"mods": {
"declined": true
},
"rev": 199,
"table": "invitation",
"type": 2,
"user_id": 29689
}

Expected behavior

Declining an invitation does not result in a 'disallowed change'
