Bug with js indexer, when index equals 0x0

[maxkatz6]

Minimal repro

1. Create new console project (netcoreapp3.1 in my case)
2. Add reference to Jint, version = 3.0.0-beta-1715 (which is latest in my case)
3. Put code below into Main method:

var shouldBe1 = new Jint.Engine().Execute("var t = '1234'; var a = t[0x0]").GetValue("a");
Console.WriteLine(shouldBe1);
Console.ReadLine();

Expected result: "1"
Actual result: undefined

In the chrome devtool`s console I can see expected result with same JS code.
With '[0]' instead '[0x0]' everything works as expected.

Any other hex value work as expected.

var t = '1234'; var a = t[0x1];

Expected result: "2"
Actual result: "2"

So problem exists only with [0x0]

Thanks for reporting this, I've prepared a PR that should fix the issue #711 .
