fix: improve error messaging for Windows logon (#219)

Summary:

The current code structure for logging on and loading the user profile
blurs the line between password-related logon failures, and agent-user
permission-related logon failures.

Solution:

Break-up the code that's in a single try-catch to split it into multiple
try-catches.
