Steve Howell 4b095cbad1 Make "assert" global in the node tests.
In the early days of the node tests we didn't have an index.js
driver, so each test set it up its own environment.  That ship
has long since sailed, so now we just require assert in index.js
as a global and make it so that the linter doesn't complain.
