fix(bootstrap peers): fix network not ever contacting bootstrap peers

well, this one is funny. In a refactor a while ago, I missed switching
conf.BoostrapAddrs -> conf.QriBootstrapAddrs. The result of this oversight
is qri connect bootstraps to *no* peers, which means the network seems
empty. Sad emoji. Programming is hard.
