### Please describe the problem.
An encrypted remote is added to a working git annex repository (mind ":~/" in the remote add command). However, after that any git annex command fails. 

### What steps will reproduce the problem?
    > git remote add encrypted gcrypt::ssh://git@gitlab.com:~/gitlabname/reponame.git
    > git push encrypted master
    gcrypt: Repository not found: ssh://git@gitlab.com:~/gitlabname/reponame.git
    gcrypt: Setting up new repository
    gcrypt: Remote ID is :id:abcdefghijklmnopqrst
