Email address update field bug

[numanturle]

version: NodeBB v1.15.0-beta.23
git hash: ccddbb1

The e-mail is not trim in the profile update area, so multiple users can use the same e-mail.

socket.emit("user.changeUsernameEmail", {
    password: "THISPASSWORD",
    email: "EMAIL",
    uid: USER_ID
}, function(e) {
    console.log(e);
});

Output:

{message: "[[error:email-taken]]"}

socket.emit("user.changeUsernameEmail", {
    password: "THISPASSWORD",
    email: " EMAIL",
    uid: USER_ID
}, function(e) {
    console.log(e);
});

Output:

null
