use_server_future does not caching server function calls correctly

[ealmloff]

Problem

#2236 polls the use_server_future again on the client which causes server functions called directly in the future to be fetched again.

Steps To Reproduce

Steps to reproduce the behavior:

• run the axum-hello-world example
• view the network tab
• observe the server function API call

Expected behavior

The server function return should be cached on the server and sent to the client serialized into the HTML
