Personalization typo

If anyone can add the update hook, this can be released faster. I might not get to it before wednesday.

I've created a MR for this one..

@Maintainers pls review this.

@Sourav_Paul Are you able to add update hook too, for potential installs that already have config on the wrong config key?

@andreasderijcke Working on it.

@andreasderijcke I've added update hook, Could you please merge it?

@Sourav_Paul Some feedback:

• I'm not sure how, but you have seemed to have overwritten the first commit on the merge request with the second. Following the git commands here on on the MR itself, it should be no problem to add commits to an existing MR. Something to double check in the future.
• About the update hook, 2 aspects:
  • The convention is to keep update hooks in the .install file, not .module and follow the existing update hook numbering unless to indicate major version jumps, which is not the case here.
    So the last one was 10001, so this one becomes 10002 and not 11001.
  • Update hook code itself was good, just didn't take possible language override into account.

In anyway, thanks for helping out.

@nightlife2008, thanks for reporting and patch.

Thanks @andreasderijcke for your feedback, I'll keep this in mind for future.
