Moved setup function into top level __init__

Discovered that the remote module also relies on the git executable as
such it also needs to be “refreshed” anytime the git executable is
updated or changed. This was best solved by moving the setup function
into the top level __init__ where the setup simply calls
git.cmd.Git.refresh and git.remote.FetchInfo.refresh.
