Add Spark.awaitStop() to after()

[victornoel]

See despegar#14.

Basically, it is needed to to get Spark.awaitStop() added to the after() method to ensure the Spark server is properly stopped (because stop() executes in a Thread).

Hi @victornoel. This change has been included in the version 1.2.0. Unfortunately I cannot upload a new artifact version to central repository yet, because I had to change the groupId (I no longer work for Despegar) and I have to register the domain. Until then, please build the develop branch and release it locally.
Regards
Fernando.

@ferwasy thank you, do you have some kind of ETA of when this will be available on Maven central or an issue to track the progress? Cheers
