Resolved OAuth2 mobile app loop

When a Pega OAuth2 authorize endpoint was invoked and the redirect URI contained "app", a loop was created where the system attempted to fetch the app alias from the state parameter value and was redirected back to itself. This could sometimes result in inconsistent mobile app styling. Investigation showed that a certificate with keyword app that was picked for the redirect URI could have the key word assumed to be the app alias context, so a workaround was to remove the app keyword. To resolve the issue, the system has been updated to look for the app alias only in the state parameter rather than performa a string contains check on the entire query string.
