Bug description

When cloning via jgit clone a non public HTTPs Git repository like https://github.com/Netcentric/calendar-sync.git it prompts for the username three times.

jgit.sh clone https://github.com/Netcentric/calendar-sync.git asks for the username three times:

Cloning into 'calendar-sync'...
Username for null: 
Username for PROXY github.com:443: 
Username:

Expected behavior

The username prompt should appear only once triggered via https://github.com/eclipse-jgit/jgit/blob/master/org.eclipse.jgit.pgm/src/org/eclipse/jgit/console/ConsoleCredentialsProvider.java. But instead the custom Authenticator https://github.com/eclipse-jgit/jgit/blob/master/org.eclipse.jgit.pgm/src/org/eclipse/jgit/console/ConsoleAuthenticator.java is triggered twice before (once for the regular server and once for a proxy)
