Roundtrip calls from the ledgerApi should include clientOptions

Test Plan

1. Create empty profile folder
2. Create a file called promoCode in the profile folder with the KAM253 promo
3. Run Brave with LEDGER_VERBOSE=true

After about 20-30 seconds, you should see the following output (originally it wasn't dumping any information into the terminal):

<<< PUT https://laptop-updates.brave.com/promo/initialize/nonua
<<< content-type: application/json; charset=utf-8

Original Issue

This was something that @kjozwiak and I noticed during a working session. clientOptions such as verboseP are not passed in any of the roundtrip calls in ledger.js, (Just is {}) see:

https://github.com/brave/browser-laptop/blob/master/app/browser/api/ledger.js#L2109
https://github.com/brave/browser-laptop/blob/master/app/browser/api/ledger.js#L2181
https://github.com/brave/browser-laptop/blob/master/app/browser/api/ledger.js#L3105

The bat-client sends all of the current clientOptions in each round trip call, so there is some missed networking debug output when running LEDGER_VERBOSE=true.

This is a very small item but we should change this so that all outgoing ledger related requests are displayed.
