fix(federation): Allow federation file sharing when federation app is…

[nickvergessen]

… disabled

The app id might be misleading, the federation app is for syncing addressbooks with trusted servers. It is not always enabled and show not have to be.

• "Regression" from feat(federation): auto-accept shares from trusted servers #49973

Steps

1. Disable app "federation" (description: "Federation allows you to connect with other trusted servers to exchange the account directory.")
2. Try to share a file federated
3. Sender log shows:

   Server error: POST https://nextcloudf32.local:442/index.php/ocm/shares resulted in a 501 Not Implemented response:␊{"message":"Share type "user" not implemented"}
