#122 Warnings after "New Contact" & no lastname entered

[katzlbt]

TABR displays tons of PHP warnings when creating a new contact and not entering a lastname.

The problem is that the new attach property to an address feature incorrectly assumes that $refid is set.

I fixed 2 major sources of warnings by skipping an address if the refid is not set.

PaggeContactEdit #679
if(!isset($a['refid'])) // if someone leaves the lastname blank we reedit the same contact - would cause tons of warnings
$a = null;

This blanks out a just entered address, which might annoy a user.

Still to fix:
Notice: Undefined index: refid in /srv/www/tab3/lib/frontEnd/PageContactEdit.class.php on line 310

I fixed all warnings, BUT ...
TODO: the input to addresses should not be lost, so a better fix on #679 is needed.
