Remove user name from git URL in itom.version() -> itom_GIT_URL

[M. Gronle]

If one clones the Bitbucket git with its username, e.g. from https://[e-mail]/itom/itom.git, the username is
included in the itom_GIT_URL variable of the itom.version() request. This is unnecessary. The username should be removed.
