to make goreportcard a bit happier https://goreportcard.com/report/github.com/docker/docker also found that `TestCpToErrDstParentNotExists()` was partially broken, because a `runDockerCp()` was inadvertently removed in f26a31e80cfcc77daba0872ddb14bf03f4398311 `TestDaemonRestartSaveContainerExitCode()` didn't verify the actual _Error_ message, so added that to the test, and updated the test to take into account that the "experimental" CI enables `--init` on containers. `TestVolumeCLICreateOptionConflict()` only checked for an error to occur, but didn't validate if the error was due to conflicting options.
