Will allow for tests to be enabled in google3 as pub or portions of pub are used to run VM tests. Previously the test harness was configured to look for a URI with a data: scheme to determine if it was being run via pub run test (pub generates its own harness and spawns the test from that). We were parsing the test URI out of this data URI, which wouldn't work correctly in google3. This change assumes that if Platform.script.scheme == 'data', the test is being run via pub from the root directory of the package. In that case, we can assume there is a 'test' directory and simply use 'test/$scriptName'as the path for the testee process.
