BasicAuth redirect removes QueryString from originalPath

[robmaas]

Describe the bug

When configuring a SitePassword Azure Static Apps will redirect any visitor to .auth/basicAuth/login?originalPath=.
After providing the password the app will redirect back to the originalPath.

However if the original URL contains a querystring the app will strip it from the originalPath and redirect to path without querystring.

To Reproduce
Steps to reproduce the behavior:

1. Configure a Sitepassword
2. Go to https://yourapp.azurestaticapps.net/test?qs=testqs
3. The app will redirect to https://yourapp.azurestaticapps.net/.auth/basicAuth/login?originalPath=test (querystring is already stripped)
4. Enter password
5. The app will redirect to https://yourapp.azurestaticapps.net/test and the querystring is lost.

Expected behavior
The app preserves the original querystring in the auth-flow.
