Erroneous "Email Address already in use" error when attempting to update profile

[johnbillion]

Steps to reproduce:

1. Visit ​https://wordpress.org/support/profile/ and click the "Edit" link
2. Change a field (such as your password) and click "Update Profile"
3. Note that the page returns an "Address already in use" error next to the Email field and your profile is not updated

This happens to you because you have three different accounts all with the same email address, which we no longer allow.

I've changed the email on the other two account that you're not using.

The message is not incorrect, just odd for that time and place. Your email address was already in use, on other accounts.

It might be good for us to fix this message so people can actually separate all of their accounts. We could warn that X other accounts are using this email and they must change X-1 of them.

Seems a bit edge-casey, since we no longer allow accounts to be made re-using emails like this. All accounts that are still this way are what, 5+ years old?

Additionally, long term, the support/profiles page will go away in favor of the new profiles page.

This is edge-case enough that we shouldn't worry about it.
