The filters section of the configuration does not check the preparator names

[fredericjaume-oc]

I was trying to filter on a specific set of tests by modifying the api-tester.yaml configuration. I added something like:

filters:
  include:
    - { id: oc_api_certification_business_partner_patch, preparator: error400XXX }
    - { id: oc_api_certification_holders_patch, preparator: error400YYY }

The preparator name does not seem to be checked, so the tests with bad preparator names will fail silently instead, it would be great to have a check for preparator name validity (maybe that's also the case for the other parameters).
