Switch OAuth flow initialization order (#1089)
Switches the order of initialization in the OAuth flow within 
the NewOAuthFlow method. Instead of initializing the 
Device Authorization Flow first, it now initializes 
the PKCE Authorization Flow first, and falls back 
to the Device Authorization Flow if the PKCE initialization fails.
