S109: Magic number -1

[nicolasbreuni]

I want to report a bug.

SonarTS version: 2.1

Node.js version: 10

TypeScript version: 3.5.3

SonarQube version: 8.0

SonarLint version and used IDE: Intellij IDEA

TSLint version: 5.20.1

Rule key: S109

Reproducer

// minimal reproducer if relevant
private readonly _id: number = -1; // No magic number: -1

Expected behavior

In the rule description -1, 0 and 1 are excluded numbers. Thus this line should not be reported.
