test: port 24 command/repository/package/util tests; add TlsHelper

Port command (9), util gitlab/forgejo/tls (6), package (6), repository (3)
tests. Implement TlsHelper. Fix porting bugs: config_command extra merge,
RootAliasPackage setters, ValidatingArrayLoader isset, repository_factory name
generation, forgejo exception code, version_parser error chaining.
