Subject: [PATCH] Fix `CoffeeScript.nodes(tokens)`; fix the repl

If you passed an array of tokens (as opposed to a string of code) to
`CoffeeScript.nodes`, its attempts to prettify error messages would break. Now
it does not attempt to prettify error messages in that case anymore (because it
is not possible to prettify the errors without a string of code).

The repl was affected by the above bug.

Fixes #3887.
