The same intergration tests as for the old endpoint.
But now using the new chunking.
We upload 3 chunks in different order and the result should be the same
in all three.
Intergration tests to ensure the share-types property is set correctly.
* Unshared item
* Shared with user
* Shared with group
* Shared by link
* Shared with user & group & link
Recent refactorings have resulted in the header being added twice, this makes browsers ignore the header which removes any security gains.
This changeset adds the header only once and adds integration tests ensuring the correct header in future.
