* simple fix for mistaken conda paths
In the previous implementation, Jedi's traverse_parents function
traversed parent directories to the system root every time. This would
inadvertently add every folder to the system root every time. Obviously,
this is not the behavior desired for the import system.
This commit collects directories in an upward search until we:
1. Hit any directory without an __init__.py, AND
2. Are above self._path.

This pull request provides a new argument to the traverse_parents
function, "root", which represents the root parent for the search. This
argument defaults to None, thereby preserving the existing behavior of
the function.
I chose to duplicate some code for performance reasons. Since I'm trying
to avoid too much path manipulation magic, we do:
* a search to a valid specified root, OR
* a simple upward search until hitting the system root when there is no
valid root specified.
On Python 3.5+, we can make use of scandir that not only list the
content of the directory as an iterator but caches some infomations (for
example, `is_dir()`; this avoid extra stats call to the underlying
filesytem and can be – according to pep 471 – 2x to 20 time faster
especially on NFS filesystem where stats call is expensive.
From a quick this is the only place where scandir would make sens, as
most other places only require the name.
