Stats: Fix stats setting role toggles not sticking

[kangzj]

Fixes https://github.com/Automattic/jpop-issues/issues/9445

Proposed changes:

• Calling setState in the constructor of a React class component does not work because the component is not yet mounted, and React explicitly prevents the use of setState during this phase. Instead, we should directly assign values to this.state in the constructor.

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
• Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

It works as described, and the changes look good to me! 👍🏼

Looks good to me!

In addition to the setState() issue, testing for countRoles here would appear to be a bug.

[kangzj]

Ya it was a bug and I fixed it by the way 😄

[a8ck3n]

Minor suggestion but maybe this array is a good candidate for a const value.
