Renewing existing membership with Pay Later incorrectly sets membership status to Current AND extends membership end date

To recreate:

• Create Student membership with start date = May 29, 2008, status will correctly show as Grace
• Modify sample online Membership Signup form to allow Pay Later
• Go to online Membership Signup as anonymous user and select Student Membership, enter same email address as associated w/ above membership, and select Pay Later
• Submit online membership

Results:

• Membership end date for the existing Student membership is extended by 1 year
• Membershp status is now Current
• Pending contribution record is created and linked to membership

This means the membership is good for another year regardless of whether the payment is ever received. Not good.

For pay-later (and IPN) renewals, membership status and dates should NOT be update UNTIL payment is received.

• • Verify the fix for PayPal Std / IPN flow as well.
