The code in the bgp extcommunity-list function was using
argv_find to get the correct idx. The problem was that
we had already done argv_finds before and idx was non-zero
thus having us always set the seq pointer to what was last
looked up. This causes us to pass in a value to the
underlying function and it would just wisely ignore it
causing a seq number of 0.
We would then write this seq number of 0 and then immediately
reject it on read in again. BOO!
Actually handle argv_find the way it was meant to be.

If we have something like:
```
ip route 1.1.1.0/24 Null0
!
router bgp 100
no bgp ebgp-requires-policy
neighbor 192.168.0.2 remote-as 200
!
address-family ipv4 unicast
network 1.1.1.0/24
redistribute connected
exit-address-family
!
line vty
!
```
1.1.1.0/24 is not advertised due to martian nexthop (0.0.0.0). It starts
working only when we use `redistribute static`.
By checking if it's a BGP static route we able to announce
1.1.1.0/24 with `network 1.1.1.0/24` without redistribute even when
`bgp import-check` is enabled.
Disabling `bgp import-check` works as well, but it's enabled by default
since 7.4.

unicast and labeled-unicast share the same table, but configuration should
be visible for both independently. Without this fix it confuses a bit
because when you enter `network 10.0.0.0/24` under labeled-unicast it's
written in unicast family block.

The problem is that peer_af_array returns NULL when SAFI is changed to
unicast. We use unicast table, but peer is created and activated under
labeled-unicast, hence we should lookup with a proper SAFI id.
Without this patch peer_af_find() returns NULL and we can't show
PfxSnt in `show bgp summary`.

Without specifying a default afi/safi we get a segfault:
