Original commit message:

    [heap-profiler] Fix a use-after-free when snapshots are deleted

    If a caller starts the sampling heap profiler and takes a snapshot,
    and then deletes the snapshot before the sampling has completed, a
    use-after-free will occur on the StringsStorage pointer.

    The same issue applies for StartTrackingHeapObjects which shares the
    same StringsStorage object.
