[expect] optimize compare nodes

[Connormiha]

Summary

Removed needless checking for isEqualNode because it checked before.
Used lazy checking for second object.

Test plan

Thanks for this! Obviously the check is completely unnecessary in some cases. Questions:

1. Where did typeof a.isEqualNode === 'function' go? It looks necessary at a quick glance.
2. Any idea how expensive isDomNode is in terms of ops/sec? Just curious.

Where did typeof a.isEqualNode === 'function' go? It looks necessary at a quick glance.

This has already been checked inside isDomNode

Any idea how expensive isDomNode is in terms of ops/sec? Just curious.

Very cheap, but expect can be inside for loop is some test cases.

Thank you for improving the calling code after my too-hurried change to isDomNode in #8064

@Connormiha Forgot to notice no line under Chore & Maintenance in CHANGELOG.md

Can you please merge changes from jest/master to avoid conflict, and then add the line, so I can merge your contribution.

I did rebase from master @pedrottimark
