Add compatibility against Pytest 5.4+

The direct construction of nodes is deprecated since Pytest 5.4 [0]:
> The construction of nodes now should use the named constructor
from_parent. This limitation in api surface intends to enable
better/simpler refactoring of the collection tree.
    This means that instead of MyItem(name="foo", parent=collector, obj=42)
one now has to invoke MyItem.from_parent(collector, name="foo").
