Conftests are plugins with a location attached to them while other
plugins do not have a location. When ordering fixturedefs those from
plugins without a location need to be listed first.
When the conftest.py files are looked for intially they got loaded
starting from the subdir ending at the parent dir(s). Later on during
collection any conftest.py files are loaded starting from the parent
dir ending at the subdir. Due to how extending fixtures works the
latter is correct as otherwise the wrong fixture will be available.
So this changes the initial conftest loading to start at the root and
go towards the subdir.
This does also affect the order of other hooks, hence the order of the
reporting being different in testing/test_terminal.py.
