chore(k6): Fix function context test (redwoodjs#9368)

**Problem**
Follow up to redwoodjs#9358 which didn't completely fix the broken tests.

**Changes**
1. Correct the function test.
2. Update to run the servers in the project not the framework. 

**Status**
You can now see the expected results which show function context is not
isolated when running the `rw-server` but is isolated for `rw serve api`
