Fee details for additional participants missing from email confirmation when registration is confirmed from edit participant form

NOTE: This is the second half of the fix we made in 3.0.4 (CRM-5559). The confirmation email is quite confusing and misleading w/o the additional participant fees listed.

Subtotal line-items for multiple participants are missing from the confirmation email sent to primary participant from Edit Participant form. To recreate:

• register for multiple participants w/ Pay Later
• go to Edit Participant for primary participant and set participant status = Registered and contribution status = Completed and check "Record Contribution" and Send Confirmation.
• the email sent to primary participant shows correct Grand Total but is missing the fee detail rows for secondary participants
