[Godot Physics] Cylinder collision detection unstable with move_and_slide (3.2.4.rc5)

[e344fde6bf]

Godot version:
3.2.4.rc5.official

OS/device including version:
NA

Issue description:
Using move_and_slide on top of a cylinder collision shape gives unstable collision results. is_on_floor() rapidly oscillates between true/false while walking across the cylinder, and if you stop in certain places it will continue to do this even if you don't move.

Steps to reproduce:

Use move_and_slide() on top of a static/kinematic body that has a cylinder collision shape. As you walk across the cylinder is_on_floor() will give inconsistent results.
