Get returns causes exception "Value is not a valid ISO 8601 format."

[DangerLifter]

On call "get returns' bol.com Api returns some dates in format "2019-05-15T17:09:38.137+02:00" which causes Assert\InvalidArgumentException: Value is not a valid ISO 8601 format.
Problem with milliseconds part in date time string.

Here is final stack in one of my cases:

() at app/vendor/beberlei/assert/lib/Assert/Assertion.php:2752
Assert\Assertion::createException() at app/vendor/beberlei/assert/lib/Assert/Assertion.php:2403
Assert\Assertion::date() at app/vendor/bol-com/retailer-api/src/Model/DateTime.php:16
BolCom\RetailerApi\Model\DateTime->__construct() at app/vendor/bol-com/retailer-api/src/Model/DateTime.php:30
BolCom\RetailerApi\Model\DateTime::fromString() at app/src/Command/Returns/ImportCommand.php:37

And one more similar place:

In Assertion.php line 2752:

[Assert\InvalidArgumentException (214)]
Value is not a valid ISO 8601 format.

@DangerLifter Dates should be converted already in https://github.com/ho-nl/BolCom_RetailerApi/blob/master/src/Handler/Rma/GetAllReturnsHandler.php#L50-L51

Are you able to create a failing test for this?

Handler processes "registrationDateTime" but issue with "processingDateTime"
