Fix serious regression in gcrypt and encrypted git-lfs remotes. Since version 7.20200202.7, git-annex incorrectly stored content on those remotes without encrypting it. Problem was, Remote.Git enumerates all git remotes, including git-lfs and gcrypt. It then dispatches to those. So, Remote.List used the RemoteConfigParser from Remote.Git, instead of from git-lfs or gcrypt, and that parser does not know about encryption fields, so did not include them in the ParsedRemoteConfig. (Also didn't include other fields specific to those remotes, perhaps chunking etc also didn't get through.) To fix, had to move RemoteConfig parsing down into the generate methods of each remote, rather than doing it in Remote.List. And a consequence of that was that ParsedRemoteConfig had to change to include the RemoteConfig that got parsed, so that testremote can generate a new remote based on an existing remote. (I would have rather fixed this just inside Remote.Git, but that was not practical, at least not w/o re-doing work that Remote.List already did. Big ugly mostly mechanical patch seemed preferable to making git-annex slower.)
