Added `AgentAPITest.LaunchNestedContainerWithUnknownParent` test.
This test verifies that launch nested container fails when the parent
container is unknown to the containerizer.

Cleaned up container on launch failures in composing containerizer.
Previously, if a parent container was unknown to the composing
containerizer during an attempt to launch a nested container
via `ComposingContainerizerProcess::launch()`, the composing
containerizer returned an error without cleaning up the container.
The `containerizer` field was uninitialized, so a further attempt
to remove or destroy the nested container led to segfault.
This patch removes the container when the parent container is unknown.

> `LAUNCH_NESTED_CONTAINER` and `LAUNCH_NESTED_CONTAINER_SESSION` leads to
> segfault in the agent when the parent container is unknown to the composing
> containerizer. If the parent container cannot be found during an attempt to
> launch a nested container via `ComposingContainerizerProcess::launch()`, the
> composing container returns an error without cleaning up the container. On
> `launch()` failures, the agent calls `destroy()` which accesses uninitialized
> `containerizer` field.
