Last issue, I promise ;). When the user has no birthdate, there's just a bullet point saying "not provided" with no indication that it's referring to a birthdate.

You should pass either the date or the "not provided" text to the `lookupuser-birthdate` message. Like the registration bullet point: [1](https://github.com/Wikia/app/blob/dev/extensions/wikia/LookupUser/LookupUser.body.php#L235-L239)[2](https://github.com/Wikia/app/blob/dev/extensions/wikia/LookupUser/LookupUser.body.php#L254).

So, you could do something like:
```
if ( isset( $user->mBirthDate ) ) {
	$birthDate = $wgLang->date( $user->mBirthDate, true );
} else {
	$birthDate = wfMessage( 'lookupuser-no-birthdate' )->text();
}
$wgOut->addWikiText( '*' . wfMessage( 'lookupuser-birthdate', $birthDate )->text() );
```
