Errors running Page.getResourceTree in DevTools e2e tests

This only happens for legacy navigation. I also can't reproduce this outside of the DevTools e2e tests or on e2e tests locally.

These are the only places where Page.getResourceTree is called. We only call it to get the main frame id:

lighthouse/core/gather/driver/execution-context.js

Line 64 in 437eb4d

const resourceTreeResponse = await this._session.sendCommand('Page.getResourceTree');

lighthouse/core/gather/driver/network-monitor.js

Line 98 in 437eb4d

const resourceTreeResponse = await this._session.sendCommand('Page.getResourceTree');

Perhaps we can avoid the error by getting the frame id using a different method.

I think I'm going to try replacing calls to Page.getResourceTree with Page.getFrameTree to get the main frame id. If the error persists I'll try tracking the main frame id via Page.frameNavigated events which we are already tracking in both files.

Haven't seen this since #14663, I'm gonna close but will keep an eye out.
