rpc: Make ValueFromAmount always return 8 decimals
This is the format that was always returned to JSON clients. The difference was not noticed before, because VREAL values are post-processed by univalue. By implementing the functionality directly it breaks the dependency of rpcserver on utilmoneystr. FormatMoney is now only used for debugging purposes. To test, port over the formatting tests from util_tests.cpp to rpc_tests.cpp.
