[BUG] Custom avatar on integrations not respected

[bkraul]

Description:

Incoming hook integrations are not using the specified custom avatar for posting of messages, and are instead using the default rocket.cat avatar. This issue is related to #14038 which seems to have been already corrected.

Steps to reproduce:

1. Deploy latest docker develop image.
2. Create an incoming webhook integration. Set a custom avatar in place of the default.
3. Trigger the webhook.
4. See that the custom avatar is being ignored.

Expected behavior:

The specified avatar should be used, which was the original behavior.

Actual behavior:

Rocket.cat avatar shows up.
