Add more tests

[MeikeWeiss]

Since we decreased the package dependencies we use the log environment instead of the example environment. Thus some methods do not have tests, e.g. AllSimplicialSurfacesByEssentialButterflyInsertion.

Other methods: AutomorphismGroup, SubsurfaceByFaces, IsIsomorphic, AutomorphismGroupOnVertices/Edges/Faces, IsAutomorphismDefinedByVertices/Edges/Faces, AllToriOfSimplicialSphere, AdmissibleRelationsOfSurface
