Pressing save and ignoring the error when editing contact allows duplicate email to be shown

Hey guys!

Working through the book and loving it!

I noticed that in the edit functionality if you ignore the errors for a duplicate or empty field it shows the incorrect information when you then press back. It is visible with the duplicate in the list. I thought it was just my code so I cloned the repo but it seems to have the same bug.

It doesn't look like it actually saves it to contacts.json but shows incorrect email on /contacts route even on refresh. If I shut down the flask server and restart it. it reverts to the correct email.
