## Current Behavior
<!-- This is the behavior we have today -->
`forEachExecutorOptions` will not run the callback if `target.options`
is undefined.
This means that even if a target exists with an executor, the target is
not being processed if it does not have `options`.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Run the callback anyway even if `target.options` is undefined
