Fix connecting to default servers with TLS more than once with ERC
Fix connecting to default servers with TLS more than once with ERC

The erc//servers function removes the :ssl variable from the list so it
can be passed directly to erc-tls, but this means that subsequent
connections will not use TLS. Thus, we should operate on a copy of the
list instead.
