Ensure that napi_throw() is able to throw a primitive value, and
document that it is able to throw any JavaScript value.

Not sure if the line above should also be corrected:
`[in] error`: The `napi_value` for the `Error` to be thrown. ->
`[in] error`: The `napi_value` for the error to be thrown.

I actually changed it to

- `[in] error`: The JavaScript value to be thrown.

I fixed a warning during the CI-lite. I'd actually like to run a full CI, because this includes code as well as doc: https://ci.nodejs.org/job/node-test-pull-request/14600/

I comment on the commit itself but here for convenience:

These tests do not test anything besides that the function call throws. The value as error validation does not verify anything. It is a no-op.

When I check for throwArbitrary it is actually not even showing up as property on test_error? So I get an test_error.throwArbitrary is not a function error.

I get this back when running Object.getOwnPropertyNames(test_error)

[ 'checkError',
  'throwExistingError',
  'throwError',
  'throwRangeError',
  'throwTypeError',
  'throwErrorCode',
  'throwRangeErrorCode',
  'throwTypeErrorCode',
  'createError',
  'createRangeError',
  'createTypeError',
  'createErrorCode',
  'createRangeErrorCode',
  'createTypeErrorCode' ]

@BridgeAR you're right! I guess assert.throws() cannot be used for arbitrary thrown values. I'll simply do the try/catch by hand.

As for the missing property, that's weird. throwArbitrary is in the list for me.

@gabrielschulhof seems like the addons were not properly rebuild on my machine earlier. That is why I had issues with the missing property. I somehow had a weird state and had to explicitly reset everything addon related before they wanted to recompile.

Replace assert.throws() with an explicit try/catch in order to catch
