fix(nextjs): Small integration test runner fixes

[lobsterkatie]

This PR fixes a few small bugs in our test runner for nextjs integration tests:

• Debug mode failed because of a missing import
• Test runner options couldn't be passed except by hard-coding them in the bash script called by yarn
• One of our node/nextjs compatibility checks was checking the wrong version of nextjs
• Console breadcrumbs caused ever-larger events to be logged, since each time an object including breadcrumbs was logged, the entire object then became a breadcrumb in the next object logged, which itself became a breadcrumb in the next one, and so on and so forth
• In the test-runner bash script, our variable keeping track of exit code was reset unnecessarily (if it's anything other than 0 by that point, the script already will have bailed)
• Our test filtering was case-sensitive

It also makes a few small changes to make debugging those tests easier:

• When comparing objects, the actual value is now stored as a variable, so that the value will be shown inline by the debugger
• The default value of the depth option is now included in its help text
• console.log(inspect(...)) was changed to console.dir(...), which does both in one, and color is now included in the output

Suggested change

const { inspect } = require('util');

[kamilogorek]

Valid only after utils/common.js replaces it with JSON.stringify. But then depth option wont work unless substituted with a correct depth-aware stringifier.

[lobsterkatie]

Hang on, though - what's the reason we want to replace inspect with JSON.stringify? What if we just use console.dir(), as it takes a depth argument and also can print different value types in different colors?

[AbhiPrasad]

I forgot about the depth option, we should just keep using inspect then, I don't think we want to replace.

Could you also please add these 3 changes?

They were overwritten in the #3788 PR, but thankfully I have local copy 😅

[kamilogorek]

TIL console.dir accept options in node api
