fix: check that view is not destroyed before creating node views in core Editor

[yyjlincoln]

Changes Overview

Adds a check before creating node views in the core editor so setProps is not called on a destroyed view.

Implementation Approach

Added checks in createNodeViews() in Editor.ts.

Additional Notes

This should be no-op for successful use cases. There should not be any reason to call this.view.setProps on a view that has been destroyed, and doing so should either be no-op or results in unexpected crashes. This PR fixes this behaviour.

Related to #5333.
