Fix definition of TableInputGeneratorMixin

[f4lco]

The definition of TableInputGeneratorMixin should probably not contain references to the DefaultFileInputGenerator. The former version created the following exception and did not make any TableInputGenerator available to my algorithm.

com.fasterxml.jackson.databind.JsonMappingException: Could not resolve type id 'DefaultTableInputGenerator' into a subtype of [simple type, class de.metanome.algorithm_integration.input.TableInputGenerator]

For reference this is the algorithm I used to reproduce the issue:

public class BugAlgorithm implements InclusionDependencyAlgorithm, TableInputParameterAlgorithm {

  private static final String KEY = "table-input-key";

  @Override
  public ArrayList<ConfigurationRequirement<?>> getConfigurationRequirements() {
    final ArrayList<ConfigurationRequirement<?>> requirements = new ArrayList<>();
    requirements.add(new ConfigurationRequirementTableInput(KEY,
        ConfigurationRequirement.ARBITRARY_NUMBER_OF_VALUES));
    return requirements;
  }

  // remainder omitted - empty methods; at most debug output
}
