Undo test reduction from HR-377

I just discovered that the Syntax Conformance test that was originally testing all entites that support custom data only supports a subset due to HR-377.

It seems there was a problem testing entities like Campaign in the HR context so testing was removed from the SyntaxConformance test - which is not cool,

We are now only testing a hard-coded map from that ticket

static $componentMap = array(
'Contribution' => 'CiviContribute',
'Membership' => 'CiviMember',
'Participant' => 'CiviEvent',
'Event' => 'CiviEvent',
'Case' => 'CiviCase',
'Pledge' => 'CiviPledge',
'Grant' => 'CiviGrant',
'Campaign' => 'CiviCampaign',
'Survey' => 'CiviCampaign',
);

but we were testing the full list of supported entities ie contact variants +

static $extendsMap = array(
'Contact' => 'civicrm_contact',
'Contribution' => 'civicrm_contribution',
'ContributionRecur' => 'civicrm_contribution_recur',
'Membership' => 'civicrm_membership',
'Participant' => 'civicrm_participant',
'Group' => 'civicrm_group',
'Relationship' => 'civicrm_relationship',
'Event' => 'civicrm_event',
'Case' => 'civicrm_case',
'Activity' => 'civicrm_activity',
'Pledge' => 'civicrm_pledge',
'Grant' => 'civicrm_grant',
'Address' => 'civicrm_address',
'Campaign' => 'civicrm_campaign',
'Survey' => 'civicrm_survey',
);
