[FIX] l10n_cl: traceback on printing invoice without setting vat in company

when the vat is not configured in the company and on printing the invoice, the traceback is raised.

this is due to the calling of method _format_dotted_vat_cl that excepts the vat value as input, when the method is called without a vat value, the traceback is thrown.

add an if condition to check there is a vat configured in the company and then the  _format_dotted_vat_cl method is called only when there is a value in vat.
