Tests for Edit Profile Page

**Goal**
We want to be able to automatically test the Edit Profile page to build confidence in the basic functioning of the site after deploys.

**Success Criteria**
- [ ] Test that confirms the following functionality of the Edit Profile page
- Users cannot edit the profile of another user
- Users can edit their own profile info, including:
- Name
- About bio
- Twitter handle / LinkedIn URL
- Legislators
- Notification Settings (Enable/Disable + Frequency)
- Users can make their profile private (if currently public) and public (if currently private)
- Should additionally verify that the user's testimony shows up as being written by in both the Browse Testimony page and Testimony Detail page while the profile is private
- Will leave it up to developer discretion whether profile privacy is complex enough to warrant splitting into a separate test
- This has been an malingering bug and may be worth an E2E test to confirm it really works with our TypeSense installation, especially coming from the Browse Testimony page.
