Add Check for Invalid iKey

[JacksonWeber]

If an invalid iKey is passed to application insights we should disable statsbeat.

It began to throw exception! Which is i think wrong behaviour for minor version change (2.9.1->2.9.2), if exception not catched, app will die! Error: Instrumentation key not found, please provide a connection string before starting Application Insights SDK. at NodeClient.TelemetryClient

Can I see what you're using to initialize the SDK on your side? I don't believe this change should be throwing that error for you, but happy to take a look.

Thank you for reply! I have reproduced it. Was confused that uncaught exception happened after 70sec of uptime. No reason to create project. It has only 1 file and 1 dependency in package.json: This programm will die in 70sec

import appInsights from 'applicationinsights';

appInsights.setup('foobar').start();

let sec = 10;
setInterval(() => {
  console.log(`uptime=${sec}seconds`);
  sec+=10;
}, 10000);
console.log('started');

......... uptime=70seconds ApplicationInsights:Instrumentation key was invalid, please check the iKey [] /path/to/thisproject/node_modules/applicationinsights/out/Library/Sender.js:199 _this._shutdownStatsbeat(); ^

If version locked to "applicationinsights": "2.9.1", this example works forever.

I see. https://github.com/microsoft/ApplicationInsights-node.js/pull/1259 should address this issue and will be included in the next release.
