Update the Testcases + Travis Integration

[sgraband]

Tests now have a seperate workspace for easier execution and to make them more robust. Currently the tests are running in a third Travis Build, next to the maven and yarn builds. However, since the tests require maven and yarn to be run, these tests could be put together in the future.

Right now two tests are failing due to #103.

Resolves #17.

@CamilleLetavernier seems like i forgot to take the changes of #140 into account. However i have trouble getting the current master to run. When i try to run yarn locally i get the following error:
error [email protected]: The engine "node" is incompatible with this module. Expected version ">=10.10.0". Got "8.17.0" error Found incompatible module.
Running 'yarn upgrade' gives me the following error:
error [email protected]: The engine "node" is incompatible with this module. Expected version ">=10". Got "8.17.0" error Found incompatible module.

Do you know what could cause this or how to fix it?

You need to install/use Node 10.x:

Node.js >= 10.11.0 AND < 12.x.
Preferably, use version 10.15.3, it has the active LTS.
Node.js 11.x is untested.
Node.js 12.x is unsupported.

Apparently, the required Node version for Theia changed in 0.9.0

Ok so i updated my node version and improved the tests for the new GLSP version.

It seems like the update broke the layouting(#142), therefore another two tests are failing.
