[Membership 2 Pro] After changing email for user, it is still showing the previous email

Hi,

the email address is not changed after I change the email address. As my tests shows, the email address is actually changed for the user in the database, but still showing the previous email address.

Steps to reproduce:
- Create a new member.
- List all members.
- Click on the "Subscription Details" link to edit the user.
- Change the email address.
- Click on the Save button.

You will see, that the email address will not be changed, the plugin is still showing the previous, original email address for the user.
