nmarklund10/ add home page testing; refactor home page component by breaking it out into separate modules

[nmarklund10]

Description

I implemented initial testing of the Home page or where the user logins. There are 7 tests:

1. An error message shows when the postLogin fails (and the $router is not called to switch components)
2. No error message shows when the postLogin succeeds (and the $router is called to switch components)
3. The modal is visible when the user clicks the "Forgot Password" link
4. The Welcome message is rendered on the home page
5. The Tutorial and its slides are rendered on the home page
6. An error message shows in the password reset modal when postReset fails
7. A success message shows in the password reset modal when postReset succeeds

As I was building the tests, I noticed that there were opportunities to break out the component into smaller modules to prevent the messy code with showing alerts and the modal.
