Soft Credit Info Wiped When Recording Credit Card Contribution

This was tested and reproduced in a client environment as well as one of our dev environment running 4.6.7, not sure how to reproduce on demo environment as this seems to be occurring only with credit card contributions and does not seem to be payment processor specific (i.e. client is using iATS, dev site testing was conducted via authorize.net). To reproduce:

1. Create new credit card contribution
2. Select required information (financial type, amount, etc.)
3. Enter soft credit contact
4. Enter credit card information
5. Save
6. Click to view/edit the completed contribution - no soft credit information remains

Thanks!
