Remove 'test-id' and 'test' commands

[mikewalch]

These were created to simplify running WebIndex. With the creation of the dev server (run via webindex dev), they are no longer needed for several reasons:

1. For simple testing, users will probably just use webindex dev
2. For complicated tests, developers can just create a script to replace functionality of test and test-id.
3. They add a lot of complexity to webindex script.
