Issue Overview

A user notified us of two sentences that are grammatically incorrect.

Expected Behavior

All sentences should be correct.

Current Behavior

These two are bad:

1. "Payment Abandoned: The this donation was not been completed" (found here https://github.com/woocommerce/woocommerce/blob/master/includes/wc-template-functions.php#L1890)
2. "The email already active for another user." (found here: https://github.com/WordImpress/Give/blob/master/includes/user-functions.php#L373)

Possible Solution

The texts should be this instead:

1. "Payment Abandoned: This donation was not completed."
2. "This email address is already in use by another donor."
