py.path.local('/').join('foo') should return '/foo' not '//foo'

See #84!

@AndreasLoow lol, just as i decided to just do the same - i'd much prefer to merge yours however

[RonnyPfannschmidt]

im most curious as to why the build fails now

[AndreasLoow]

Not sure ... it fails on the following test:

_____________________ TestPOSIXLocalPath.test_join_to_root _____________________
self = <test_local.TestPOSIXLocalPath object at 0x7f0435c9cc88>
path1 = local('/tmp/pytest-of-travis/pytest-0/test_constructor_equality0')
    def test_join_to_root(self, path1):
        root = path1.parts()[0]
        assert len(str(root)) == 1
>       assert str(root.join('a')) == '/a'
E       assert '//a' == '/a'
E         - //a
E         ? -
E         + /a

But when I try it locally it works:

>>> root = path1.parts()[0]
>>> root
local('/')
>>> assert len(str(root)) == 1
>>> root.join('a')
local('/a')
>>> assert str(root.join('a')) == '/a'

@AndreasLoow i determined its the issue i found in #130 - tox-dev/tox#536 is taking a toll on pylib

[RonnyPfannschmidt]

merged as the error is urelated and stems from the tox issue
