Failed propType when loading from snapshot

To reproduce:

• Create a snapshot in development
• Load it in a new tab

Observe the warning:

VM21:37 Warning: Failed prop type: The prop `projectKey` is marked as required in `Instructions`, but its value is `null`.
    in Instructions (created by Connect(Instructions))
    in Connect(Instructions) (created by Workspace)

    in Connect(Workspace) (created by Application)

まず、issue に記載されている snapshot ワークフローを再現します。development snapshot を作成し、その後、新しいタブで読み込みます。snapshot の読み込み中に、Instructions コンポーネントとその projectKey prop を追跡します。報告されている required-prop warning なしで snapshot が読み込まれれば完了です。
