Summary:
Provide a more robust technique for exporting the mocks to a file.
The current technique for exporting mocks to a file seems to fail under some scenarios. The correct format is an array of objects:
```
[
{
"requestUrl": "https://api.github.com/repos/facebook/yoga",
"requestMethod": "GET",
```
However, the following format is sometimes exported instead:
```
{
"10": {
"requestUrl": "https://demo9512366.mockable.io/SonarPost",
```
Using `Object.values` provides a more robust technique that has been successful during subsequent testing.
