Complete scalacheck testing for http requests

[Zak Patterson]

Testing should have a client implementation available, and define properties to submit tests

For example:

1. User signup
2. User login
3. User posts feature
4. User cannot upvote feature

Ex 2:

1. User login
2. User gets list of features
3. User upvotes feature with comment
4. User gets list of features - verify vote in feature

Scalacheck testing is working well
