An optional priority integer (higher equals more important, and therefore that the listener
will be triggered earlier) that determines when a listener is triggered versus other listeners
(defaults to 0). If two listeners have the same priority, they are executed in the order that
they were added to the dispatcher.
Changing the priority from -1 to 1 will make sure this event is executed before composer-extra-assets, which uses priority 0.
Fixes compatibility with https://github.com/koala-framework/composer-extra-assets.
