Refactor error handling in data explorer Part 3 (#315)

- Make sure we pass the error message string instead of an error object when we call `TelemetryProcessor.traceFailure` since TelemetryProcessor will call `JSON.stringify` on the error object which would result in an empty object
- Removed ErrorParserUtility since it only works on specific error types. We can just log the full error message and manually derive information we need from the message.
- Added option to include stack trace in `getErrorMessage`. This is useful for figuring out where the client side script errors are coming from.
- Some minor refactors
