Duplicate tmpdir fixtures causes --fixtures sorting logic to fail

[martinpelikan]

It looks like something (recent) in pytest-splinter is creating a duplicate tmpdir fixture, and causes py.test --fixtures to fail when trying to sort the available fixtures.

I can't tell if this is due to something unique/incorrect in pytest-splinter, or if pytest itself should be made more robust.

Please see the details I filed in: pytest-dev/pytest#1651.

importation of fixtures is always a bad idea

@RonnyPfannschmidt
cool, but what exactly is the proposed solution then?

[RonnyPfannschmidt]

@bubenkoff in that particular case for now use the tmpdir factory for pytest 3.1 we have a invocation scoped tmpdir fixture planned

@martinpelikan please check with 1.7.4 which is just out

@bubenkoff Confirmed working on 1.7.4, thanks!
