fix ipv6 handling for remotes/sync jobs

* add square brackets to ipv6 adresses in BackupRepository if they not
already have some (we save them without in the remote config)

* in get_pull_parameters, we now create a BackupRepository first and use
  those values (which does the [] mapping), this also has the advantage
  that we have one place less were we hardcode 8007 as port

* in the ui, add square brackets for ipv6 adresses for remotes
