This reverts commit b64eb0622b6c5e59eeb2161223e793ba4164ceb9.

[EGD-5783] Exclude empty body from response message

Remove body field from response message,
if it contains null. Add 204 and 501 status codes
and use them in proper responses.
204 stands for success but no content, and 501
means endpoint is not implemented.
Additionally some minor fixes.

[EGD-6191] Fix harness call tests

* This PR provides a fix for the bug reported in [EGD-6081].
The solution adds the `tear_down`-like fixture called after the
problematic tests, that enforce focus on `ApplicationDesktop'`s
main window.
* Additionally similar solution was added to `test_auto_lock`
to restore original (30s) lock timeout.
