rewire workaround for NodeJS 12

[breautek]

Platforms affected

Android tests

Motivation and Context

Fixes jasmine output on NodeJS 12.
Fixes #768

Description

Rewiring the process object no longer works as of NodeJS 12. However you can still rewire members of the process object. This PR rewires individual process members as required by the test, instead of rewiring the process object entirely.

Testing

I've ran npm test and observed full jasmine output on Node 12. Note, due to another issue as reported #767 here, there is still 1 test failing on NodeJS 12.

I've also ran the tests successfully on NodeJS 10.

Checklist

• I've run the tests to see all new and existing tests pass
• I added automated test coverage as appropriate for this change
• Commit is prefixed with (platform) if this change only applies to one platform (e.g. (android))
• If this Pull Request resolves an issue, I linked to the issue in the text above (and used the correct keyword to close issues using keywords)

FYI Travis CI failed on the first time Node.js 8, turned green after I restarted that job. This looks like a transient failure that is not related to this change.

• the workaround test code is clean
• build remains green on Node.js 6, 8, and 10
• I see that Modifying globals within module leaks to global with Node >=10 jhnns/rewire#167 does not appear when running npm test on Node.js 12

FYI these updates will be superseded by PR #783, which is basically a simpler solution that we think is slightly more correct.

The explanation is that using spyOn generally blocks the actual function unless .and.callThrough() is chained on. I just found a nice article here: https://hatoum.com/blog/2016/11/12/jasmine-unit-testing-dont-forget-to-callthrough
