Change subject: ari: Ignore invisible bridges when listing bridges.
......................................................................

ari: Ignore invisible bridges when listing bridges.

When listing bridges we go through the ones present in
ARI, get their snapshot, turn it into JSON, and add it
to the payload we ultimately return.

An invisible "dial bridge" exists within ARI that would
also try to be added to this payload if the channel
"create" and "dial" routes were used. This would ultimately
fail due to invisible bridges having no snapshot
resulting in the listing of bridges failing.

This change makes it so that the listing of bridges
ignores invisible ones.
