Description

This issue surfaced with a regression in the resourcefields component shim used by the Save Submission action.

Previously, I could call getComponent('keyToLayoutComponent' from a nested component instance (e.g. in the Developer Portal application's resourcefields component shim, which calls that function to get a Panel component). However, with the introduction of the new pathing regime, this broke because we omit layout components by checking the component JSON for the input property.

This PR updates that change to allow for layout components to be retrieved using getComponent using just their key.

Since there is evidence (described in the PR description) that we should expect getComponent to include layout components, I've changed this default parameter.
