[TYPO3-english] realName and email is removed when saving BE user settings

[Guillermo R. Oramas J.]

Hello.

I have some users and I don't want they change their realName or email, so
I config their tsconfig with:

setup.override.realName = 1

setup.override.email = 1

In the user settings they are showed disabled, with the user realName and
email grayed.

When the user click in Save Settings these field are cleared and the the
data is lost.

Do you know something about this issue?
