Title:
  Segfault in tests when calling subsearch() with MockScope

Status in unity-scopes-api package in Ubuntu:
  Fix Committed

Bug description:
  Getting crash with the below stacktrace. After a quick look I think
  this is because the method that checks for loops does this:

          auto scope_impl = dynamic_pointer_cast<ScopeImpl>(scope);
          auto logger = scope_impl->runtime()->logger();

  without checking if scope_impl is not null (which is the case for
  MockScope according to the comment in the code above). And I remember
  myself commenting about this is the MP for this change ;)

  Program received signal SIGSEGV, Segmentation fault.
