Self signup enrollment flow without approval dies because of tandcAgreement permission calculation

A self signup enrollment flow that does not require approval can die because the tandcAgreement permission step is not calculated properly.

The code in CoPetitionsController.php in the calculatePermissions() method currently has

$p['tandcAgreement'] = $isEnrollee;

Instead it should probably have the same logic as the lines above that line for the checkEligibility step.
