Due to the update of the mockito versions, we are now able to run the emf tests again also in the p2 build
New version is not available via orbit, consume missing via org.eclipse.emfcloud.modelserver.tests bundle
Add mockito dependency libs to tests bundle
If emf.tests are running via p2 the test resources are saved differently, hence let's execute tests on resources in a .temp directory to avoid having git changes on each p2 build.
Resolves #167
