core: apply manual IPv6 configuration earlier when RA is also used (rh #1101809)

Browse source 
Reporter left SLAAC enabled (because it's default and requires being
explicitly turned off) and added manual IPv6 address.  They expected that
address to be assigned very soon after starting the connection, but it was
not assigned.

This happened because NM waits for RA before assigning any IPv6 configuration,
including the manually specified addresses.  In the reporters case, there was
no IPv6 router on the network, so NM waited indefinitely for a router
advertisement and never applied any IPv6 configuration.

It seems reasonable to apply any IPv6 configuration we have available, when
we have it.  We already apply RA configuration before starting DHCP, and
apply DHCP configuration if/when we get that.
