6 cleanup - Githubissues

Use shared examples to stub out current_user and define as user within a let block.
- For future tests that need a logged-in user, use the following code within the top of your describe block and user can be called by simply calling user (no @ needed!):
```
# example feature spec
describe 'user profile page: current user', type: :feature do
context 'when I log in as an authenticated user' do
  include_context 'logged in as authenticated user'
  [...]
end
end
```
Backfilled PORO tests
Added spec type at the top of each spec file (e.g. type: :feature)
Updated pull request template styling
Refactored routes:
- Dashboard
- Profile
- Registration
- Logout
Refactored facades and services by abstracting out to individual facades and services
- Each service now inherits from BackEndService to get the .db_conn and .parse_json class methods
