current user update failed but session updated !

[YousefAlsbaihi]

Issue Description

If the current user want to change his Email/username normally Parse check if username used by other user and if it is used it will return error, now this is good and work perfectly so far but the issue is the session is automatically updates to the new value where it failed.

so basically the session for the current user updated even if it wasn't for the backend

Steps to reproduce

$currentUser = Parse\ParseUser::getCurrentUser();
echo "Current Username is : ". $currentUser->get("username");

if ($currentUser) {
  $currentUser->set("username", "ww");
try {
        $currentUser->save();
        echo "UPDATED";
    } catch (Parse\ParseException $er) {
        $ex = $er->getMessage();
        echo "<br> Error: ". $ex;
    }
}

Sorry for the delay? What version of Parse-Server are you using?

Is the session really updated or is the username updated locally? In the video you didn't output the session.

Can you write a failing test and describe what is expected to happen vs what actually happened?

it update everything in the user session but it doesn't in the backend
i'm using latest version using Back4App.com
however i found a solution to use $currentUser->fetch();
