[IMP] account: tests framework: add explicit label to invoice lines created with only amount, to avoid crashing in some tests

We also inject a context key to ignore prediction in case account_predictive_bills (enterprise) is installed. This way, having the same label on invoice lines generated by the helper will still behave in the same way, even if enterprise is installed.
