ReverseIterator.prev() does not point the previous iterator.

[samchon]

Summary

• TSTL Version: 2.0.14
• Expected behavior: Points the previous iterator.
• Actual behavior: Points the next one.

Code occuring the bug

import * as std from "tstl";

function main(): void
{
    let v: std.Vector<number> = new std.Vector([0, 1, 2, 3, 4]);
    let it: std.Vector.ReverseIterator<number> = v.rbegin().advance(2);

    console.log(it.prev().value, it.advance(-1).value); // 1 3 -> Incorrect, must be 3 3
    console.log(it.next().value, it.advance(+1).value); // 1 1 -> Exact
}
main();
