Bad address caching causes wrong original address records (and potentially more)

[bjendres]

In ticket #19 the address handler was refactored. The new implementation contains a grave/stupid error (see here), that stores the addresses across different calls and different contacts. In particular the recorded original address might be wrong when submitting multiple changes in the same PHP session.

Can be reproduced by Creating 2 Contact (e.g. id 10 & 11). Both have an address, and then put in two request updates for addresses in, one for each contact:

$result_1 = civicrm_api3('Contact', 'request_update', [
    'id' => "10",
    'street_address' => 'Yorckstr. 38',
    'postal_code' => '12345',
    'city' => 'Yorck',
    'country_id' => '1082',
  ]);

  $result_2 = civicrm_api3('Contact', 'request_update', [
    'id' => "11",
    'street_address' => 'testStreet 1',
    'postal_code' => '77777',
    'city' => 'Entenhausen',
    'country_id' => '1082',
  ]);

Resulting Origin Address (Ursprüngliche Addresse) remains the origin address of the first contact, as seen in the screenshots:

I did the test again with e84a8a9 active, and now origin address is correct.
