Empty .d.ts rollup emit regression in 1.2.28

• Version: 1.2.28
• Rollup Version: 2.21.0
• Operating System and version (if applicable): MacOS 10.15.5
• Node Version (if applicable): 12.18.2
• Does it work with tsc (if applicable): N/A
• Typescript: 3.9.7

Reproduction

Using this plugin produces correct (as far as I can tell) .d.ts rollups for all submodules of velcro.

However, upon upgrading to 1.2.28, the emitted .d.ts files are empty and no errors appear to be emitted either.

Reproduction can be achieved by:

1. Clone ggoodman/velcro#8f6063e43fe3fdc01d06fd38fb82455026bf8ed7
2. npm i
3. npx lerna bootstrap
4. npm run build
5. Observe that ./dist/dist-main/index.d.ts for ./packages/@velcro/bundler is empty.

All sub-packages defer to the top-level rollup factory in rollup.config.factory.js so you shouldn’t have to look further than that to see how this plugin is being instantiated.

Expected Behavior

Produces a rolled-up .d.ts file

Actual Behavior

Produces an empty .d.ts file without reporting any errors or warnings

Thanks for all your hard work on this!
