Validator behaviors fail

[crossan007]

After a recent composer update, my Propel2 validation behaviors began failing.

Error message given include:

It looks like symfony/yaml updated (since it's not specified in Propel2's composer.json file) from 3.4.35 to 4.3.8, which introduced a breaking change to Propel2's reliance on it for the validate behavior.

I resolved it by specifying "symfony/yaml":"^3.4" in my project's composer.json.

This will be interesting for #1578

I've seen some issues with yaml 3.0->3.3, I'll check deeper into it.

Do you have an example of the smallest amount of code I can use to reproduce this? It would help if you shared your composer.json and php version also.
