array-type doesn't consider "object" to be a simple type

[lambda-fairy]

Bug Report

• TSLint version: 4.5.1
• TypeScript version: 2.2.1
• Running TSLint via: CLI

TypeScript code being linted

function foo(a: object[]): object[] {
    return a;
}

with tslint.json configuration:

{
    "extends": "tslint:recommended",
    "array-type": [true, "array-simple"]
}

Actual behavior

test.ts[1, 17]: Array type using 'T[]' is forbidden for non-simple types. Use 'Array<T>' instead.
test.ts[1, 28]: Array type using 'T[]' is forbidden for non-simple types. Use 'Array<T>' instead.

Expected behavior

No warnings reported, since object should be considered a simple type along with e.g. number and string. See the TypeScript 2.2 release notes.
