Changing name of endpoint

[rahulmutt]

If we change "fibonacci" below to any string containing 3 letters (such as "fib"), you get 404 when accessing the endpoint. It works for strings of other sizes (1,2,4, etc.).

type API = "fibonacci" :> Capture "n" Int :> Get '[JSON] Value

Tested after typelead/eta#654: it prints the correct output with /fib
