Preserve .project file when doing vf upgrade --rebuild

[cecep2]

Currently, if my venv project-venv contains a .project file, this file is not recreated when I call vf upgrade --rebuild project-venv. I think it is reasonable to expect the 'rebuild' command to restore this file.

Makes sense to me. Do you think we should set the variable scope to avoid the (admittedly small) risk that a global variable with the same name has already been defined? e.g.:

if begin; set -q _flag_rebuild; or test -n "$packages"; end
            set -l install_cmd
            set -l project_file_path
            […]

Thank you! Good point - I've updated the file accordingly and also document the change in the docs.
