Update Timesketch API client "run_analyzers" "ignore_previous" handling

[jkppr]

Currently the Timesketch API client is handling if an analyzer should be run again or not ("ignore_previous" flag). However, with PR#2883 we moved this functionality into the server side API endpoint to also have the UI etc. benefit from this functionality.

Therefore, even setting ignore_previous=True in the API client does not have any effect since the server will still not run it which can lead to unexpected behaviour on the client side.

TODO: Update the API client to work with the server side checks for ignore_previous with breaking as little as possible.
