More cleanup for `optimiser/Tests` - Follow-up from "Resolve "removed unused nsga2 directory""

The following discussion from !201 (merged) should be addressed:

• @kraus started a discussion: (+3 comments)

  @gsell I removed this tests. But in optimiser/Tests there seems to be more to cleanup like Homotopy. What else?

  @snuverink_j I think also:

  • gentest.tmpl
  • gentest.data
  • generatesim.cpp
  • schedsim.cpp
  • runsim.cpp
