Fixes#6853
Canonicalize jobs first before adding any sidecars. This fixes a bug
where sidecar tasks were added without interpolated names and broke
validation. Sidecar tasks must be canonicalized independently.
Also adds a group network to the mock connect job because it wasn't a
valid connect job before!
