When the submodule git directory needs to be cloned because it is not found in .git/modules/ the clone command will write an absolute path into the gitfile. When no clone is necessary the git directory will be reactivated by the git-submodule.sh script by writing a relative path into the gitfile. This is inconsistent, as the behavior depends on the submodule having been cloned before into the .git/modules of the superproject. A relative path is preferable here because it allows the superproject to be moved around without invalidating the gitfile. We do that by always writing the relative path into the gitfile, which overwrites the absolute path the clone command may have written there. This is only the first step to make superprojects movable again like they were before the separate-git-dir approach was introduced. The second step is to use a relative path in core.worktree too. Enhance t7400 to ensure that future versions won't re-add absolute paths by accident. While at it also replace an if/else construct evaluating the presence of the 'reference' option with a single line of bash code.
