Quick fix for PhantomJS launcher

[rdodev]

The id it wanted to append to the temp directory was alphanumeric and due to the truthiness of JS it was trying to cast it to a number, which gave a NaN as a result. Forcibly casting the id toString() solved the issue.

this._tempDir = (env.TMPDIR || env.TMP || env.TEMP || '/tmp') + '/testacular-' + id.toString()

Thanks, merged as 3410c2c

I had to rebase it, so please do:

git reset --hard HEAD~7
git pull upstream master

To make it easier for you, in the future, always create a new branch per feature / fix.

Again, thanks a lot.
