any-of's reference is converted from a list of string to a single string

[Seddryck]

Apparently any-of (or within-list) is not able to read the list of possible values

The following predicate:

<predicate operand="gender" type="text">
  <within-list>
    <item>M</item>
    <item>F</item>
  </within-list>
</predicate>

is systematically returning the following error:

Test 'NBi.Testing.Core.Elasticsearch.Acceptance.ElasticsearchRuntimeOverrider.RunPositiveTestSuiteWithConfig("ResultSetEqualToResultSet.nbits")' failed:
	System.ArgumentNullException : Value cannot be null.
Parameter name: source
	at System.Linq.Enumerable.Contains[TSource](IEnumerable`1 source, TSource value, IEqualityComparer`1 comparer)
	at NBi.Core.Calculation.Predicate.Text.TextWithinList.Apply(Object x)
