fix(run,finishRun): don't mutate options, set default reporter to v1

[straker]

This fixes an issue where not passing an options object to axe.finishRun would result in axe not using the v1 reporter even though the v1 reporter is the default for a axe.run. This caused the results of the axe.finishRun to not include failureSummary.

const results = await axe.runPartial()
await axe.finishRun([results])  // v1 reporter not used

The better question would be why we set the v2 reporter as default when axe.run uses the v1 by default.

I'm not sure what we should do at this point. The test is failing because we need to mutate the options object to pass the normalized run options from partialRun to finishRun in order for the results of an axe.run and axe.finishRun to be the same.

The only thing I can think of is that we don't use the modified options object in the reporter but instead try to use the original options object the user uses for toolOptions. Then it will show exactly what the user used to run the results rather than our modified and normalized options.

const runResults = await axe.run({ runOnly: 'region' });
console.log(runResults.toolOptions.runOnly) //  { type: 'rule', values: ['region'] }

const partialResults = await axe.runPartial({ runOnly: 'region' });
const partialRunResults = await axe.finishRun({ runOnly: 'region' });
console.log(partialRunResults.toolOptions.runOnly) //  'region'

LGTM, but can you also get rid of the use of clone in testUtils.runPartialRecursive. We're not going to need it there anymore now that we have this in.
