test(tests): improve coverage, fix issues and errors in tests, cleanup

[MatthewDorner]

Fixes #1804 partially

• Add better coverage for GeneralInformation that tests both editable and non-editable functionality
• Cleanup and standardize component test code
• Add assertions for Thunk actions using mock store's store.getActions() as described here https://medium.com/@philihp/testing-a-redux-connected-component-with-thunk-actions-with-enzyme-41be4cc0bdce
• Standardized naming of Redux actions such as getAppointmentStart to fetchAppointmentStart so actions that fetch data are named fetch consistently
• Removed i18n log messages from test output
• Removed some warnings from test output, but not all

Test failing looks like a timezone issue. I'll look into it.

@MatthewDorner I put WIP on title so we know that is still on "working", ok?

[MatthewDorner]

Sure. I think it's just having the same test issue as the other PRs are at this time. Once that is resolved, I think this will pass.
