When IPv6 addresses have not been downloaded, use hard-coded address info
The microdesc consensus does not contain any IPv6 addresses.
When a client has a microdesc consensus but no microdescriptor, make it
use the hard-coded IPv6 address for the node (if available).
(Hard-coded addresses can come from authorities, fallback directories,
or configured bridges.)
If there is no hard-coded address, log a BUG message, and fail the
connection attempt. (All existing code checks for a hard-coded address
before choosing a node address.)
Fixes 20996, fix on b167e82 from 19608 in 0.2.8.5-alpha.
