Job fails to checkout over SSH. When created with Gitea organization and scanned for jenkinsfile. 

The problem seems to be in ssh url:

git.exe config remote.origin.url ssh:///git@gitea.f.cz:-1/F/llll3.git # timeout=10

notice the ssh:///git@

Because of this the "/git" user is used. The correct user should be "git"

When using the git plugin and Multibranch pipeline, checkout proceeds correctly.
