Affected Version is  2.1.0 (can't choose it in the form)

Steps to reproduce

1.  Define a basic requestParameterTrait via Light-Development as documented below
2. Add a component Variant with the value for the googleCampaign trait 123
3. Test the behaviour once with RequestScopedTraitStorage and once with SessionScopedTraitStorage

<light-module-name>/traits/googleCampaign.yaml

$type: requestParameterTrait
ruleField:   
  $type: textField  
  name: value
valueField:  
  $type: textField
traitStorageClass: info.magnolia.personalization.trait.storage.StorageAwareTraitCollector$RequestScopedTraitStorage

Expected results

Whether with session or request based storage, the right variant should be displayed.

Actual results

During my local test, it only worked when I chose the session based variant.
