Description of the PR

fix #1272

A model with an array property used to have the wrong PHP typehint in the setter: the array item object type instead of "array"

This is visible in the samples, in the Pet.php model: setPhotoUrls and setTags

Restarted the job. 👷

The Travis CI failure is due to the installation of Dart 2.1 (released a few days ago) so it can be ignored for now.

Looks correct. 👍
