refactor: always validate recipe

This can slow things significantly down by requiring the catalogue and
if you don't have that, cause a slow `git clone`. However, the current
behvaiour is very confusing because it never actually checks if what the
user passes is actually a recipe. `abra recipe fetch DOESNTEXIST` gives
a better error to the user now. I'm hoping we can speed up the catalogue
handling at some point.
