Jon Dufresne 1a8e992fcc Use relative imports throughout tests
The tests relied on Python2 relative import semantics. Python3 changed
import semantics to always search sys.path by default. To import using a
relative path it must have a leading dot.

Forward compatible with newer Pythons.

Works towards the goal of moving tests outside of the installed package.
