[*]:MO:MONDIAL RELAY: Fix JS bug with other modules

From now, because you just check if $res is null, it would be better to move it right before ```$point_relais``` affectation.
```php
$point_relais = $res['MR_Selected_LgAdr1'].
($res['MR_Selected_LgAdr1'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr2']. 	($res['MR_Selected_LgAdr1'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr2'].
($res['MR_Selected_LgAdr2'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr3']. 	($res['MR_Selected_LgAdr2'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr3'].
($res['MR_Selected_LgAdr3'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr4']. 	($res['MR_Selected_LgAdr3'] ? ' <br/> ' : '').$res['MR_Selected_LgAdr4'].
($res['MR_Selected_LgAdr4'] ? ' <br/> ' : '').$res['MR_Selected_CP'].' '. 	($res['MR_Selected_LgAdr4'] ? ' <br/> ' : '').$res['MR_Selected_CP'].' '.
$res['MR_Selected_Ville'].' <br/> '.$res['MR_Selected_Pays']; 	$res['MR_Selected_Ville'].' <br/> '.$res['MR_Selected_Pays'];
```
