test(application): port two doRun script-command tests

Port testNoPluginsDisablesPluginsWhenScriptCommandsExist and
testScriptCommandTakesPriorityOverAbbreviatedBuiltinCommand. Both stay
#[ignore]d because do_run panics at the script-registration todo!()
(application.rs:2461) when composer.json has scripts. Add a test-only
ApplicationHandle::__get_composer accessor so the first test's
getPluginManager assertions can be expressed.
