Update tracking response

[tomazJakomin]

Added correct mapping for tracking response.
Reordered some imports.
Added missing option class PiecesEnabled.
It contains an additional fix in mapper, because when implementing new class for ServiceHeader response I was calling wrong method on it.

@tomazJakomin What is the difference to pull request #4?

It is actually pull request #4 + fix

This is my first contribution on github that is why branches and pull request could be a little bit messed up to look at it.
I apologize and will improve in the future.

Hi @tomazJakomin, thank you for your contribution.

If the PR #4 is outdated, then please close it. Could you please briefly describe your changes (explain the feature this PR adds / issue it fixes)? What did you want to do but couldn't prior to your changes?

@tomazJakomin Despite your pending response I had a look at the changes. The PR seems to deal with the following issues:

• Class Map: add missing ResponseServiceHeader type
• Delete Shipment: fix passing Reason code from request builder to SOAP type
• Track: introduce constants for usage in TrackingRequestBuilderInterface::setPiecesEnabled
• Track: handle empty ShipmentEvent type during response processing

Can you confirm?

[tomazJakomin]

@mam08ixo I can confirm those are the issues there were fixed.

Just a note regarding the ServiceHeader and ResponseServiceHeader types: Apparently DHL Express changed the WSDL and split the original service header into two different types. With your PR, both types point to the same PHP class which offers only the common subset of fields available at the API. Good enough for me, missing fields can be added anytime if someone needs them.

Thank you for the contribution @tomazJakomin

Thanks for the approvals.

I will prepare another PR with some more updates soon.
