Describe the bug
When an "http:" endpoint is passed to the CosmosClient, it throws "Error: Cannot connect to http://x.x.x.x:xxxx while allowInsecureConnection is false.". When I patched this, it further threw "TypeError: Protocol "http:" not supported. Expected "https:"", which turned out to be a typo in how we were parsing the protocol from the Url. This error was not handled properly, so the test's unhandled exception event was fired, but it was throwing away the stack of the original exception by JSON.stringifying the error.

To Reproduce
Steps to reproduce the behavior:

1. Configure tests to use "http://localhost:8081" (note HTTP, not HTTPS)
2. Start tests
3. Observe that tests output to STDERR some unuseful JSON and a stack trace to the undhandled exception handler (but not the original exception)

Expected behavior
A clear and concise description of what you expected to happen.

1. I expect "http" endpoint to work
2. I expect to get the source error when unhandled exceptions are handled

Additional context
I am working on a PR to address this.
