Enable history archive support for all non-admin communities

Previously, we've turned archive support off by default, this means,
community member nodes won't try to download torrent data when they
receive a magnetlink.

This commit ensures that communities joined in the future will have
this setting on, and also all existing communities that the node
isn't admin of will have this feature enabled.
