hasClass with regex parameter breaks on jenkins and not locally

[reenan]

Current behavior

I have the following test:
expect(alignCenter.find('.card-item-tooltip').hasClass(/(left|right)/)).toBeFalsy();
It works fine and pass when running locally (macOS, node 12).

On jenkins when running the tests (linux, node12) this test fails with TypeError: className.indexOf is not a function.

Expected behavior

Same output locally and on jenkins

Your environment

Local: macOS, node 12
Jenkins: linux, node 12

The implication is that you're not installing the same versions of enzyme and enzyme things in those two places; this was an issue that was fixed in #2057 and released in v3.10.0 of enzyme.

In other words, this is a duplicate of #2057, and you can fix it by updating enzyme.
