What problem does this solve?
If a route is defined with component: null, Vue Router silently accepts it.
This can make import/export mistakes difficult to debug.
What does this change do?
Adds a development-only warning when a route is defined with a null component.
Tests
Added a unit test to verify the warning is triggered in development mode.
