Parsing empty `yarn.lock` fails

Expected Behavior

lockfile-lint should be able to parse any valid yarn.lock file. An empty file is a valid yarn.lock, so running lockfile-lint again it should succeed.

Current Behavior

 ℹ ABORTING lockfile lint process due to error exceptions 
 
Unable to parse yarn lockfile "yarn.lock" 

TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))
