Spatial Dataset Service created w/ CLI does not work until manually saved in admin pages

[swainn]

Tethys Version: 3.4.1

If the tethys services create command is used to create a spatial dataset service like so:

tethys services create spatial -t GeoServer -n tethys_geoserver -c admin:geoserver@http://localhost:8181/geoserver/rest/ -p https://www.example.com:8181/geoserver/rest/

attempting to retrieve the engine returns None, which can result in errors like the following:

    response = geoserver_engine.list_workspaces()
AttributeError: 'NoneType' object has no attribute 'list_workspaces'

However, this can be fixed by opening the Spatial Dataset Service in the admin pages and saving it again. tethys services create seems to be missing some important step.

This issue can be reproduced using the following docker-compose: https://github.com/Aquaveo/tethys_portal_docker_sirba

The tethys service create command is assigning the wrong value for engine here:

tethys/tethys_cli/services_commands.py

Line 197 in 6266f2c

password=service_password, engine=service_type)

It needs to assign values as is done here:

tethys/tethys_services/models.py

Line 135 in 6266f2c
