Merge #11050: Avoid treating null RPC arguments different from missing arguments

Browse Source 
745d2e3 Clean up getbalance RPC parameter handling (Russell Yanofsky)
fd5d71e Update developer notes after params.size() cleanup (Russell Yanofsky)
e067673 Avoid treating null RPC arguments different from missing arguments (Russell Yanofsky)
e666efc Get rid of redundant RPC params.size() checks (Russell Yanofsky)

Pull request description:

  This is a followup to #10783.

  - The first commit doesn't change behavior at all, just simplifies code.
  - The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
  - The third commit updates developer notes after the cleanup.
  - The forth commit does some additional code cleanup in `getbalance`.

  Followup changes that should happen in future PRs:

  - [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
  - [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
  - [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303
