Updated path following cfp-speakers services refactoring.

Updated path. App and test run.

Not sure about <script src="components/cfp-speaker/app/config.js"> addition.
Should ask to ndeloof who made the addition in the cfp-speaker app on commit https://github.com/devoxx/cfp-speaker/commit/7a866293e830d997c6557cc0e61ee66c6167fb3d

Maybe we should not rely on the one in the cfp-speakers dependency but on out own file.
