Currently, it seems that there is no way to test the behaviour of the function defined in onServerPrefetch

Describe the solution you'd like
It would be great if there was a way to trigger the serverPrefetch lifecycle hook from the tests

Additional context

Hey, maybe I am mistaken, but I cant see a way to test the behaviour I have defined in the onServerPrefetch lifecycle hook defined in a setup function in my component. With the options API, this was possible, using the following approach:

wrapper.vm.$options.serverPrefetch()

However, I can see no replacement that can be used for the composition api.
