test: port 35 auth/installer/io/zip/bitbucket tests; implement date_create

Port auth_helper (14), library_installer (8), console_io (7), zip_downloader (3),
git_bitbucket_driver (3) tests. Implement date_create/strtotime for the ISO8601/
RFC3339/relative formats Composer uses (unknown input -> None, no silent guess).
Fix production bugs: Question::is_assoc list-vs-assoc, auth_helper gitlab-domains
list handling, LibraryInstaller RefCell double-borrow, ZipArchive::extract_to
ErrorException propagation.
