console.assert should not throw error

[justjavac]

In the previous implementation #102, console.assert throws an error. I think console.assert should not throw an error.

Before Node.js v10.0.0, however, a falsy assertion would also cause an AssertionError to be thrown. This discrepancy was fixed with Node v10, so that console.assert() now acts the same in both Node and the browser.

And in https://console.spec.whatwg.org/#assert, console.assert is defined as follows:

assert(condition, ...data)

1. If condition is true, return.
2. Let message be a string without any formatting specifiers indicating generically an assertion failure (such as "Assertion failed").
3. If data is empty, append message to data.
4. Otherwise:
   1. Let first be data[0].
   2. If Type(first) is not String, then prepend message to data.
   3. Otherwise:
      1. Let concat be the concatenation of message, U+003A (:), U+0020 SPACE, and first.
      2. Set data[0] to concat.
5. Perform Logger("assert", data).

Cool - I didn't know that. Looks good.

Can you please remove the additional integration tests you added? Those are relatively expensive to run and I don't think it's warranted for this. The unit test you added is sufficient.

I have deleted the integration tests.

Shouldn't console.assert output be tested?

console.assert()

before:

Error: Assertion failed: // with U+003A (:) and U+0020(SPACE) at the end

after:

Assertion failed

I found a typo error in tests, I seny another pr #1342

LGTM - thanks
