refactoring `(record-and-run-raw)` with tests

[gkspranger]

• src/yetibot/core/handler.clj

  • created "parameter object" function (->cmd-param-map) related to the (record-and-run-raw) function
  • using new param object in (add-user-message-to-history)
  • using new param object in (handle-parsed-expr), also removed redundant binding of interp/*chat-source
  • using new param object in (add-bot-response-to-history)
  • extracted successfully handled expr result into own function (->successfully-handled-expr)
  • extracted unsuccessful handled expr (exception) result into own function (->unsuccessfully-handled-expr)
  • extracted logic surrounding the evaluation of an expression and the recording of its response into own function (eval-expr-and-record-response)
  • modified (record-and-run-raw) to use newly extracted functions and param object

• test/yetibot/core/test/handler.clj

  • adjusted tests to use new param object
  • added new tests for newly extracted functions
  • added tests for existing functions that could benefit from them

• ran tests using new install and verified commands are being evaluated and recorded
