Add current remote file list back into manifestor inputs

[hess-g]

The upload command was not passing in the list of external files to manifestor#build, which meant that every local file was being treated as new. Drive throws an exception when a file with no ID that also matches a name in the existing file is included in the manifest.

Updated. I meant to pull that console.log, but it turns out good that you saw it.
