2 step cancel process

[nmakuch]

This PR consists of the following:

Context

• More clarity was needed over the cancel feature that was previously in place
• Users found it confusing and it posed the risk of someone accidentally erasing their session without knowing the consequences

Creating a /cancel page that users are routed to after hitting cancel

• a cancel page has been created which tells the user that by cancelling their session they will lose all their current data and that their tax return will not be filed.
• Routing needed to be considered for going back and forth between the cancel page and it's previous path
• Basic unit tests have been created for the page

Changing 'Continue' to 'Next'

• Yedida has suggested changing 'Continue' to 'Next'
