Refactored scheduler test driver to avoid using uninitialized object.
The shared pointer to MockHTTPScheduler is initialized after the
library, while the library may start using it right after its
initialization via the events callback. This change removes the
shared pointer altogether and hence prevents possible segfaults.

The shared pointer to MockHTTPExecutor is initialized after the library,
while the library may start using it right after its initialization via
the events callback. This change removes the shared pointer altogether

Passed scheduler as a shared pointer into the callback.
To ensure the lifetime of the scheduler is longer than the lifetime
of the scheduler library driver, pass scheduler as a shared_ptr.
