Revert UseDefaultRedirectUri (#601)

- Revert UseDefaultRedirectUri back to localhost 
- This change broke netfx browser auth because it was returning
`https://login.microsoftonline.com/common/oauth2/nativeclient`
which is not configured as a redirect on the client app
- we either need to revert this or consider updating the client app
