Convert osm_route_member unique index to trigger (#1501)

Browse Source 
This PR changes the three-column unique index to an on-insert trigger. This should fix the issues we're having with CI failures and still achieve the behavior of coalescing duplicate routes. 

I moved the concurrency_index calculation into an intermediate materialized view to separate the de-duplication capability from both DENSE_RANK() and from imposm updates.
