Don't check 'UseMicrodescriptors 1' when calling get_network_statuses()
So much confusion around this...
https://trac.torproject.org/projects/tor/ticket/24110
It turns out in practice these methods essentially never provided
microdescriptor flavored router status entries because 'UseMicrodescriptors'
defaults to 'auto' (and it's rare to set it to '1' since that's the default
anyway). However, if that was done we stacktraced...
>>> desc = next(controller.get_network_statuses())

From what I can tell nowadays UseMicrodescriptors doesn't change the 'GETINFO
ns/all' response. As such reverting...
