Remove nil values in requests

[davidelbe]

It seems like a recent change to the Arbetsförmedlingen API gives an error any time you provide nil values.

We made a temporary fix just to get it working for our specific use case. Do you want a proper PR (with tests) or is this something you're already aware of/want to handle differently?

Hi @davidelbe. A PR with tests would be great 👍

Thanks! 🌟

@buren After further investigation it looks like this API is being discontinued in a few months, so I'm unsure we'll be doing any more work on this API version.

With the following changes we got it to work, but a migration to the new API will be needed soon. We could probably find a few clients that needs this done, and maybe save some time and money by joining other devs with the same issue?
