Title: Remove isPlaceholderOptionSelected from setPlaceholder

The placeholder should be set if any valid placeholder has been specified, not just through setting the placeholder arg when calling select2(). The new line sets the placeholder is getPlaceholder() returns a valid value (e.g. if data-placeholder, placeholder, or placeholder options are set).
