Unexpected behaviour with $this->isRoot results in composer-dev-symlink failing silently

Hi!

Just tried this module, as its exactly what i needed, thanks a lot!

But i ran in to a problem where the hooks were not fired, it was because of the $this->isRoot check.

After a bit of debugging i found out our repos that require a shared module dont have names in the composer.json, this comment helped me composer/composer#7089 (comment)

Is that behaviour intended or is this maybe a confusion when __root__ is returned? After adding the name to my project, this plugin works flawless!
