Support for functions breaks parsing of fixture data

[huanvu]

executeFunctions in fixtures-loader won't work right for values such as "123,234". After going through eval, "123,234" comes out as "123"

Model:
   model_test:
      key: "123,234"

Hi @huanvu

Thanks for your feedback.

For now as a quick fix, I suggest using "'123,234'" notation instead of "123,234"
