Clean Up App, Add Encryption Error Handling, and Add Tests

[torch2424]

As the title states, due to the professor moving up deadlines, and springing up random 13 page reports, and trust me, I just re-read the initial project documents to make sure I wasn't crazy, the front end and back end have a good amount of Tech Debt. The app started just fine, and had a lot of good things going on, but now there is alot of code just thrown around, and the schemas are REALLY bad. Like 5 objects deep to get a PGP key bad...

Also, the backend AND the frontend are half handling users by the mongo ids, and the other half by their facebook ids.

And not to mention the 20+ step process it will be to take upgrade Ionic 2 from beta 11 to RC4 or whatever current ionic version...

May these cynical gifs express the feelings of the tech debt in this project:

I had to change to User_Ids half way through the project so we could implement the group chat >_<

Also the storage for messages and the pgp keys in the db were quite janky LOL I might fix that in the future :P
