### Please describe the problem.

I was trying to follow https://git-annex.branchable.com/special_remotes/git-lfs/ (only without any encryption), to store at least some data on github via LFS (e.g., for https://github.com/dandi-datasets/nwb_test_data). 

Even though I do provide URL to the `annex initremote` call, it is not stored within `remote.log`:


[[!format sh """
$> sudo rm -rf /tmp/testds2 && ( mkdir /tmp/testds2 && cd /tmp/testds2 && git init && git annex init && git annex initremote gh-lfs autoenable=true type=git-lfs url=git@github.com:yarikoptic/testds2.git encryption=none && git show git-annex:remote.log; )

git annex 7.20190912-1~ndall+1


If I just proceed, populate and copy some data via lfs (example uses datalad's `create-sibling-github` to create a new repo): 

[[!format sh """

on a new clone I get a complaint that `url=` is missing, and no data is fetched

[[!format sh """

  You appear to be using ssh to clone a git:// URL.
  Make sure your core.gitProxy config option and the
  GIT_PROXY_COMMAND environment variable are NOT set.

  Remote origin does not have git-annex installed; setting annex-ignore

  This could be a problem with the git-annex installation on the remote. Please make sure that git-annex-shell is available in PATH when you ssh into the remote. Once you have fixed the git-annex installation, run: git annex enableremote origin

so I had to enableremote it while providing URL I become able to `get` the file:

[[!format sh """
$> git annex enableremote gh-lfs autoenable=true type=git-lfs url=git@github.com:yarikoptic/testds2.git encryption=none && git annex get 123                                         
enableremote gh-lfs ok      
(recording state in git...)
get 123 (from gh-lfs...) 
(checksum...) ok
(recording state in git...)
"""]]


Shouldn't that URL be recorded in remote.log? (similarly to `type=git` remotes)
