tests: bgp_l3vpn_to_bgp_vrf test needed to correct order

Browse Source 
The bgp_l3vpn_to_bgp_vrf test is looking for a prefix
on multiple routers that the ordered received is non-deterministic.
As such the regex's are failing occassionaly when the
route is received in an unexpected order.

One possible order:

BGP displays the paths in the order received since it's just a linked list.
For this test modify/add the luCommands to track that we may
receive the paths in a non-deterministic order.
