fixtures: always returna a new directory with DotGit. (#169)

DotGit now creates a new temporary directory on every call. This
allows test to easily get multiple copies of the same repository
(e.g. to test fetch/push cases). It also ensures that tests do
not have side effects on other tests unless they share the path
from the same DotGit call.
