chore(RTTR): Prevent warn log in test

[satelllte]

The change prevents console.warn output log pollution, as well as covers it with test.

Example of log from the latest run in master branch:

PASS packages/test-renderer/src/__tests__/RTTR.events.test.tsx
  ● Console

    console.warn
      Handler for onPointerUp was not found. You must pass event names in camelCase or name of the handler https://github.com/pmndrs/react-three-fiber/blob/master/packages/test-renderer/markdown/rttr.md#create-fireevent

      28 |     }
      29 |
    > 30 |     console.warn(
         |             ^
      31 |       `Handler for ${eventName} was not found. You must pass event names in camelCase or name of the handler https://github.com/pmndrs/react-three-fiber/blob/master/packages/test-renderer/markdown/rttr.md#create-fireevent`,
      32 |     )
      33 |
