Remove unnecessary List mock causing mockito builder issues

Errors look like:

  Invalid @GenerateMocks annotation: Mockito cannot generate a valid mock class which implements 'List' for the following reasons:
    The method 'Iterable.reduce' features a non-nullable unknown return type, and cannot be stubbed. Try generating this mock with a MockSpec with 'unsupportedMembers' or a dummy generator (see https://pub.dev/documentation/mockito/latest/annotations/MockSpec-class.html).
