getComposerRoot() returns empty string in ^1.3

The method getComposerRoot() returns an empty string in version 1.3.0

Can confirm this
For me also getVendorDir returns empty string.

I investigated a little bit.
This actually works in drupal and drush.

But I was using drupal finder in post-install-cmd and post-update-cmd composer scripts. Where both getComposerRoot and getVendorDir return empty string. Both worked as expected with old DrupalFinder class.

I don't know if this package is supposed to support this use case.

Anyway both can be replaced with:

• getVendorDir: $event->getComposer()->getConfig()->get('vendor-dir');
• getComposerRoot: realpath(dirname(\Composer\Factory::getComposerFile()));

#73 should fix this issue.
