if partialSearchPaths is an empty array, resolvePartialName errors

if partialSearchPaths is an empty array, resolvePartialName catches an error it should allow.

I'm encountering the following error when trying to run path resolution with an empty partialSearchPaths array.

The array is _.map-ed to promises, and passed to Promise.any. The error being thrown is by bluebird because it does not like an empty array being passed to Promise.any. In the event that the user explicitly passes an empty partialSearchPaths array, this code should be smart enough to not pass an empty array to Promise.any, and instead rely solely on the ingredient path resolution logic.
