[Bullet] Angular limits in Generic6DOFJoint doesn't work

[wacyym]

Godot version:
3.1.1

OS/device including version:
Win 7

Issue description:
Im trying to use rigid body physics for car simulation with 6DOF Joint
Angular limits in Y/Z axis enabled, but wheel still can rotate around Y/Z axis.
This parameters doesnt work for me:
angular_limit_x/softness
angular_limit_x/restitution
angular_limit_x/damping
angular_limit_x/force_limit

Steps to reproduce:
Arrow keys - control vehicle.
Accelerate, turn in any direction - rear wheels will be rotated in Y/Z axis, despite of angular limits

Minimal reproduction project:
Car Using Physics.zip

After some resarch - problem can be solved using angular motors instead using applying torque for each wheel...
Function as designed?

@madmiraal Could you check if this is (still) valid?

[madmiraal]

The bug is valid.

workaround: dynamicsWorld->getSolverInfo().m_numIterations = 50;

workaround: dynamicsWorld->getSolverInfo().m_numIterations = 50;

based on your suggestion i figured out that more precise joints will just need more iterations.
a cheap workaround is to duplicate the same joint like 5 to 10 times. so if anyone out there desperately needs it to work just like me, duplicate the same joint for more iterations.
