We remove the last few calls to UpdateAccount from the
TestAccountService test. Previously, the UpdateAccount call was used in
this test to also _insert_ new accounts and to force the account ID to
be set to specific values. So here we need to instead call the store's
NewAccount method to insert a new account, then we get the AccountID
from the returned value and we need to then use this returned ID (which
is no longer forceable) in the remainder of the tests.
In our mission to replace UpdateAccount, we need
UpdatAccountBalanceAndExpiry to take a negative balance so that we can
use it to replace the behaviour of UpdateAccount as it stands today.
In this commit, we remove one call to the UpdateAccount store method and
replace it with a call to a new UpdateAccountBalanceAndExpiry method
which updates an accounts balance and/or expiry fields and finds the
account via the given ID. This method signature is more appropriate for
a SQL backend than the UpdateAccount method.
Update the accounts `Store` and `Service` interfaces take a context.
This is in preparation for when the backend DB of the accounts service
is a SQL store which will have methods that take a context.
This commit adds a prefixed logger that is then used to log trace
information about a payment. This will make it easy to see from the logs
which account ID is making the request, what the request ID is and what
the relavant payment hash is.
In preparation for implementing trace logging that makes it easy to link
state across requests and responses for more informative logs, we add a
new ReqIDToPaymentHashStore interface along with an in-memory
implementation. This can be expanded in future to contain other state
but for now let's just go with the payment hash since that is useful to
have and will provide the user useful information about the payment
corresponding to a log.
