Test case for simulation reset with detachable joints

[mjcarroll]

🦟 Bug fix

Summary

This test exercises resetting a world with a detachable joint.

The simulation starts with an arm (simple_arm) and an object to be manipulated(object).
When simulation runs:

• At t=1.0, the arm is aligned with the object (x=+0.15),
• At t=1.1, the arm forms the detchable joint
• At t=3.0, the arm moves over the end of the table (x=+0.3)
• At t=5.0, the simulation is reset

If physics and reset are implemented correctly, when the position of the arm is reset to x=-0.06, the block should not follow or stay attached via the detachable joint.
If physics and reset are implemented incorrectly, the block will move with the arm and fail the test.

I believe this is down to only established flaky tests.

I disabled the test to follow suit with the rest of the windows tests of this nature.
