list: behavior in no-scm projects

[pared]

Upon running:
dvc list .
inside my home directory, I get following output:

ERROR: failed to list '.' - Failed to clone repo '.' to '/tmp/tmpwy4abbuldvc-clone': Cmd('git') failed due to: exit code(128)
  cmdline: git clone --no-single-branch -v . /tmp/tmpwy4abbuldvc-clone
  stderr: 'fatal: repository '.' does not exist
'

Having any troubles? Hit us up at https://dvc.org/support, we are always happy to help!

Shouldn't this message be simpler, like . is not an Git nor DVC repositroy?

➕1 to improving this error message to something more friendly like `dvc list` can only list contents of Git-tracked DVC repos. (Note that it doesn't support no-scm DVC projects.)

This works now, since we are using Repo.open() these days instead of always clonning. Closing
