transaction id missing in some cases (338)

[AlexP11223]

Sometimes the order will not receive a transaction ID. The order is difficult to locate in the PayPal dashboard as a result.

Steps to reproduce

1. Set intent to "Authoirze".
2. Create new order & pay for it.
3. Capture authorized order via order action OR capture in PayPal dashboard (may need to wait 2-3 min for webhook).

OR

1. Set intent to “Capture" or “Authorize”.
2. Create new order & pay for it using a saved card.

Expected behaviour

Transaction ID should always be added to the order details.

Also maybe we should set the ID for authorizations before capture too (and replace it with capture ID when available). The same URL format seems to work for viewing authorizations.
