Fix calledWith(objectContaining) when there are multiple calls

[ecraig12345]

Summary

#15038 introduced an issue (#15501) where expect(fn).toHaveBeenCalledWith(expect.objectContaining(...)) would not work if the function was called multiple times, due to mutation of the sample state after each non-matching call.

const f = jest.fn();
f({ a: 1, b: 2 });
f({ a: 3, b: 7 });

// fails because the sample was mutated to be { a: 1, b: 7 }
expect(f).toHaveBeenCalledWith(expect.objectContaining({ b: 7 }));

This PR reverts the change and adds tests which will catch the issue if it's re-introduced.

Initially I thought I'd found a way to fix the issue and preserve the formatting improvements, but while adding tests, I found some cases where the failure messages were misleading (extra "expected" object properties shown that weren't originally present--example). I couldn't think of a way to fix that case without adding a new option to pretty-format, so it seemed best to just revert the change since correctness is more important than improved formatting.

Test plan

Existing tests pass (one snapshot changed due to the revert). Added tests which would detect if this issue is re-introduced.

Fixes #15501
