Fix stale WRENN_SANDBOX_ID and WRENN_TEMPLATE_ID after snapshot restore

Browse Source 
After restoring a VM from snapshot, envd had already completed its initial
MMDS poll, so the metadata files in /run/wrenn/ and env vars retained values
from the original sandbox. Call POST /init after WaitUntilReady on both
resume and create-from-template paths to trigger envd to re-read MMDS.
