Fixed / Refactored majority of Unit (non CI) tests to run green based on current functionality

[telnetdoogie]

Tests should now run green with the exception of the test_webapp and CI / Integration Tests.

@thess updated tests only, to match current functionality.
Apologies for the false PR earlier, I had included a merge in there from your previous commits, wanted to get this cleaned up to only include my modifications and based from your latest commit in fmsentry.

I am not able to run the Integration tests (test_indicators , test_modem, test_voicemail) based on my dev platform / hardware setup, and I haven't taken a stab at the test_webapp at all. Just wanted to make sure that the majority of logic / function tests were able to run green.

I guess it is apparent that I do not use these test units or CI as they are from the original project. I do however, appreciate you bringing these up-to-date (more or less). I will merge this after I get a chance to try them out.

The original documentation (Wiki) is a bit stale too -- hint, hint.

The test_wepapp test after I looked at it is pretty pointless to be honest, my recommendation would be to just delete that one.

I found it very useful when doing the nomorobo updates to try to do it test-first as it did actually help me find some edge cases that I hadn't accounted for, or where one change broke another. Running at least those ones regularly might also give an indicator when nomorobo or shouldianswer.com services have changed (or just that the test numbers need to change to validate continued functionality)

FYI I've made this my "procrastination project" - so when I have something really gnarly in front of me that I need to do, I'll probably just open this one up instead and procrastinate instead... if you see PRs from me it means I'm avoiding real life ;)

I'll take a gander at the wiki too next time I need to procrastinate on an urgent but uninteresting thing :)

You might want to take a look at the issues and tag some of them with help wanted as well if you think there are some low hanging fruit that folks can help out with.

I couldn't figure out how to contribute to the wiki. Best I could do was fork this repo and create a wiki there which I can edit, but there is no pull request functionality for wiki. I made a couple of small changes to the install instructions here in my own fork but I couldn't figure out how to apply the changes to yours.
