chore: updating tests for new way of requesting JWT tokens in mender-…

…connect

This PR is made to change the mocks and testflow in tests to better fit the new implementation of the PR 👉 mendersoftware/mender-connect#134. This PR fixes it so `mender-connect` requests a new JWT token on its own, so its not dependent on `mender-update` to do so. Previously `FetchJWTToken()` wasn’t called which wouldn’t let it call the JWT token independently, which made it dependent on `mender-update`. The proposed fix is using `FetchJWTToken()` to fetch the token, to then for `WaitForJwtTokenStateChange()` to retrieve it in it’s waiting. The old mocks and test flow for the tests seemed to be more tailored to test the functionality with `GetJWTToken()`. This PR proposes a change in the mocks and test flow to better test the new implementation.
