When calling package.createPackage() errors do not result in a rejected Promise

[richclement]

When calling package.createPackage(...) and an error is generated, the code does not reject the Promise. Instead the error bubbles up in the .then().

package.createPackage({
   packageName: 'name',
   packageDescription: 'description',
   metadata: [{tag: 'source', value: 'sec.gov'}] // tag is case sensitive and should be `Source`
}).then(res => {
   // res is the error returned from the server
}).catch(err => {
   // flow should go through catch
});
