ConversionService is able to deal with empty collections and nested collections (fixed regression; SPR-7289, SPR-7293); ConversionService properly handles nested Resource arrays in Map values (fixed regression; SPR-7295); ConversionService does not accidentally use copy constructor for same type (SPR-7304)
