Bug: Circular references in props cause "Maximum call stack size exceeded" since v2.4.5

[JeppeKnockaert]

Describe the bug
When a property contains a circular reference, vue-test-utils gets stuck in a loop, resulting in a "Maximum call stack size exceeded" error.

To Reproduce
Failing example (2.4.5): https://stackblitz.com/edit/github-mhdk9j-cpr5hr?file=src%2Fcomponents%2F__tests__%2FHelloWorld.spec.ts&view=editor&startScript=test:unit
Working example (2.4.4): https://stackblitz.com/edit/github-mhdk9j-gdhwv2?file=src%2Fcomponents%2F__tests__%2FHelloWorld.spec.ts&view=editor&startScript=test:unit

Expected behavior
The test should not crash on circular references, because Vue itself also doesn't crash on this.

Hi @JeppeKnockaert

Thanks for the repro.

isDeepRef has been introduced in #2356

@Evobaso-J would you mind taking a look to see if you can fix the regression?

[Evobaso-J]

Sure! I'll try ASAP

@cexbrayat the fixes are done, but I'd rather take some more time to add several unit tests to isDeepRef.
However, since this looks urgent, I can mark the PR as ready and open a follow-up to add said tests

[cexbrayat]

@Evobaso-J We're not in a rush, take your time to add tests and ping me when it's ready to review 👍 Thanks for taking a look!

[Evobaso-J]

@cexbrayat ready! ✌🏻

I'm using vue testing library and I'm getting the error reported here (I tested with version 2.4.4 and it was working fine)

@cexbrayat When can we expect this fix to be released ?
