[@rollup/plugin-node-resolve] Allow fallbacks for dependencies with incorrect exports field on package.json

[tornadocontrib]

Either the resolve plugin fails to resolve the dependencies using exports field it should be able to fallback to main or module field

See #1704 for my potential fix

Should address the following error
