[BUG] Confusing verification email

[diegolmello]

Description:

I changed a user email and received an email asking to verify my account, but the writing is confusing.
It says "You have successfully created an account..." although I didn't create a new account.

Steps to reproduce:

1. Enable "Verify email" on server
2. Change a user email

Expected behavior:

Maybe verification emails shouldn't assume it's a new user.

Actual behavior:

Server Setup Information:

• Version of Rocket.Chat Server: 3.1.0-develop on open server

we could change Verification_email_body i18n key by removing the "successfully created an account" part. but then we should add something similar to Visit_Site_Url_and_try_the_best_open_source_chat_solution_available_today i18n key, which is used for welcome/enrolment email.

I think we need an if condition whether the mail is creation verification mail or email reset verification mail.
