Tap does not write all fields for certain streams to target

[kspeer825]

Expected: Tap-Harvest should send all fields for a given stream to the target, based on the V2 Harvest API. We are defining the expectations for which fields should be sent based on what is returned in the response of a get call to the Harvest API.

Actual: Tap-Harvest sends all fields for most streams with the following exceptions.
Stream: fields
roles: user_ids
clients: statement_key
invoices: recurring_invoice_id, period_start, paid_at, paid_date, closed_at, period_end
estimates: declined_at, accepted_at
time_entries: timer_started_at, rounded_hours

From this group the following fields were confirmed by warnings in the tap-tester logs.
Stream: fields
roles: user_ids
clients: statement_key
invoices: recurring_invoice_id

The following appear to be a test issue, not a bug. These streams are not captured as a result of not creating the necessary data to:
Stream: fields
invoices: recurring_invoice_id, paid_at, paid_date, closed_at
estimates: declined_at, accepted_at
