Small bug in deactivate() (main.js)

[dirkwhoffmann]

function deactivate() {
    return new Promise(function(resolve /*, reject*/) {
        if (null == extensionInstance) {
            extensionInstance.deactivate();
            extensionInstance = null;
        }
        resolve();
    });
}

==should be != or !==.
