Fixes #6519.
This ensures that we wrap all assets recursively when any incoming dependency is wrapped. Previously, we'd only wrap the asset the dependency pointed to, not necessarily its dependencies as well. In the test case, a has a circular dependency on b -> a. c also depends on a, but forces a to be wrapped by requiring it inside a function. However, b was left unwrapped, resulting in a
parcelRequirecall toathat ran before a's other dependencies which are still unwrapped –💥. Basically, if an asset is wrapped, all of its children also have to be wrapped, but this wasn't true in some cases due to DFS stopping when it hits a node its seen already. Now we check all incoming dependencies for each asset rather than relying on the context when hitting dependency nodes.
