Replace 'beta' with 'v1' in appInsightsUri variable

[gwenau]

I have been having trouble accessing my Application Insights until I discovered that the appInsightsUri variable is hard-coded to the beta version. Could you please update this to v1 in the applicationInsights.js and common.ts file or allow the appInsightsUri variable to be soft-coded? Thank you.
