Invoice Dashboard fails to display all invoices if unknown paymentNetwork or currency address like 'USD'

[MantisClone]

Problems

1. Invoice Dashboard fails to display all invoices if unknown paymentNetwork found.
2. Invoice Dashboard fails to display all invoices if currency address is 'USD'.
   

Impact

@MantisClone's "Alice" and "Bob" addresses cannot view invoices because they created a "USD" invoice during the RN Summer Hackathon

Proposed Solution

1. Don't throw error when parsing fails. Instead, display a - for unfound keys. Display a unsupported payment network for unrecognized payment networks.
2. Gracefully Handle non-smart-contract currencies like USD

Details

We already have a similar logic in the Invoice Drawer.
