TypeError: Cannot read property '1' of null when running with REPL

[seabaylea]

When running the following in REPL with the 1.0.2 development line:

> node
> var appmetrics = require('appmetrics');

The following TypeError is seen:

TypeError: Cannot read property '1' of null
    at getRootModuleDir (C:\Users\tunniclm\workspaces\jtctools\runtime.tools\build\Release\deploy\internal\node_modules\appmetrics\probes\trace-probe.js:187:30)

    at Array.forEach (native)

This is caused by the redundant/unused getRootModuleDir() function in probes\trace-probe.js, which can be removed.
