use a meeker test command for Git check

i'm suggesting an alternate, less eager, Git.check command. my understanding is that the "ls-remote" is a somewhat arbitrary command to check the existence of a repo (correct me if i'm wrong).

in the project i'm working on, this dumps 13,000 lines of git tags* to the console, which is a bummer.

the amended command will return a more limited list, and works for me. and will perhaps work out until someone comes along that has 13,000 branches on their repo.

then plumbing a higher log level through for this command might be worthwhile.

let me know what you think


* if this seems extreme, just imagine CI tagging a busy repo several times a day for several years
