## Current Behavior
<!-- This is the behavior we have today -->
The migration from `browserTarget` to `buildTarget` assumed config would
not be undefined.


## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
The migration should check if config is undefined
