Subject: [PATCH] fix: message in a chat opened from the sidebar fails with "is
 not valid JSON" (#32534)

Opening a chat from the sidebar while the home page was still setting up a new chat let that setup finish afterwards and clear the opened chat's id. The next message then failed with "Unexpected token 'd', "data: {"id"... is not valid JSON" and the chat's tags did not load. The new chat setup now stops once another chat has been opened. Signing in to an OAuth tool still turns it on together with the model's default tools.

Follow-up to #32488
