Don't send the address verification email "From" the user in question

Summary: Sending these as the user doesn't make a ton of sense, and LLVM reports some issues with these emails getting caught in spam filters. Users expect these emails, so just send them from "noreply@example.com" or whatever is configured.

Test Plan: Sent myself a verification email, verified it came from a noreply@ address.
