[BUGFIX] Fix select with multiple enabled not being saved correctly

If the 'multiple' field in the fieldConfig is set the
$newDatabaseValueArray is returned as is, with duplicate entries. If this
is not the case $newDatabaseValueArray is returned as before, being
modified with the array_unique function.
