inspector.url()/open() does not work if NODE_V8_COVERAGE is set #46110

What steps will reproduce the bug?

$ NODE_V8_COVERAGE=/tmp node -p "inspector.url()"
undefined
$ NODE_V8_COVERAGE=/tmp node -p "inspector.open()"
node:inspector:172
    throw new ERR_INSPECTOR_ALREADY_ACTIVATED();

How often does it reproduce? Is there a required condition?

100%

What is the expected behavior?

I would expect, regardless of whether NODE_V8_COVERAGE is set, to be able to inspector.open() if there is no inspector.url(), and then after calling that be able to access inspector.url()

What do you see instead?

If NODE_V8_COVERAGE is set, inspector.url() is undefined but inspector.open() throws an error.

It looks like new inspector.Session().connect() does still work in case, so we could 'fake' the inspect server as a workaround, but this is a complex hack.
