Pruned tx is requested with /address/Ds... all tx fail to load

[alexlyp]

When a tx is not found via RPC request during Address.update it errors out incorrectly.

Appears that getTransaction in app/controllers/transactions.js has incorrect callback return.

Should return err and null txinfo, then above it should catch the err and carry on loading tx

@alexlyp, I hope you are talking the about the insight-api codebase for "Appears that getTransaction in app/controllers/transactions.js has incorrect callback return."

currently error message is "Appears that getTransaction in app/controllers/transactions.js has incorrect callback return.", It refers to https://github.com/decred/insight-api/blob/23d38a0bfcc3cafebe9318d288891512fff33eb1/app/controllers/transactions.js#L96

Please let me know for this ticket can I work on insight-api, or needed to create separate ticket on insight-api.

[alexlyp]

Yes, please do any work on insight-api that you deem necessary.
