add bug

[Ughuuu]

Made a PR so you can view the bug I am experiencing. Here is the image of how the example looks like:

What is happening here, I am calling the parry::query::contact and getting No collision, even though the shapes are obviously colliding.

From my investigation, the code goes to epa2.rs

And then it stops at:

if niter > 10000 {
    return None;
}

It seems to be adding the same face over and over 1000 times to the heap and removing it, and then it stops.

In the end bug only happens with capsule. So I ended up making the capsule from 2 circles and 1 square.

I couldn't compile this specific branch so I updated with master: https://github.com/Vrixyz/rapier/tree/add-bug_updated ; I can reproduce the bug.
