TypeError: Path must be a string. Received undefined

Hi all. There is an issue that prevents me from handling an error case.

Reproduction steps:

1. Obtain a .zip file, that doesn't actually contain any shapefiles.
2. Use ogr2ogr(pathToZipFile).exec((error, data) =>{ ... } to read said zip file.
3. The following error is produced and uncaught.

TypeError: Path must be a string. Received undefined

Other relevant information:

• NodeJS Version 6.10.0 / NPM version 3.10.10
• ogr2ogr GDAL 1.10.1, released 2013/08/26
• og2ogr (node module) version 1.0.0
• OS: Ubuntu 14.04

The callback to the .exec method is invoked, with a "No valid files found" error, as expected, but the NodeJS process then crashes due to the uncaught exception sometime later in that routine.

Fixed in 1.0.1
