Local serializers.yml has no preference

[jmcolmenar]

Describe the bug
Properties in a local serializers.yml file have no precedence on the compiled file. Properties in command line do have prevalence.

To Reproduce

1. Include a local serializers.yml
2. Change one of the properties like activate/deactivate a serializer, with the opposite value as the compiled one.
3. Run Mork and check the results.

Expected behavior
Properties in the local file should prevail, has happens with applications.yml

What happens instead
Properties in a local serializers.yml are not taken into account.
