Routing: Allow implementing other search routes than /search in other router services

[tkohr]

Description

This PR introduces uses getSearchRoute() instead of ROUTER_ROUTE_SEARCH within the router.facade to allow implementing other search routes than /search in other router services.

Note: Needs to remove ROUTER_ROUTE_HOME from the datahub-router.service to work (which is not part of the path due to a redirect).

It's quite curious that this always worked

[tkohr]

Yep, maybe due to the redirect in lines https://github.com/geonetwork/geonetwork-ui/pull/850/files#diff-18147f3d9fd25936e42e709dea85cb97a42c69b44e19d92cde9d43f409ad6baaR30-R34 above...

Oups I also forgot about it and missed the notification today. I think there is still an issue, when looking at the e2e tests. I'll take a look when coming back from holidays.
