Backed enumerations with values not of type `string` cannot be used in customized TestDox output

[pdobrovolny]

The exception is thrown when using an provider and one of the parameters is an enum of type int

fix example:
NamePrettifier::objectToString() on line 292

if( $enumReflector->isBacked() ) {
  return (string)$value->value;
}

Trace:
