fix(live-server): testing (#1331)

* fix(test): "TypeError: options.assets is not iterable"

* fix(test): "TypeError: Cannot read property 'address' of undefined"

* fix(test): "should not inject script into svg files"

* fix(test): corrected the package-name

"Uncaught AssertionError [ERR_ASSERTION]: version not found"
the package got renamed with commit 420f3ea

* fix(testing): corrected those conditions

it's not clear why those conditions shouldn't get negated for that specific testing scenario

* fix(tests): "removing" these tests as they are still in "todo" phase

* fix(tests): eslint feedback in the necessary return

* fix(tests): eslint feedback on newer variables/constants declarations

* fix(tests): exiting mocha at the end by its version 3 behavior

instead of the changed behavior by version 4

* Update index.js

* chore(test): removed unfinished testcases

* chore: prettier feedback
