Issues trying to auto-import across project boundaries

TypeScript Version: 3.2.2, 3.3.0-rc

Search Terms: autoimport, project references, autocomplete

Code
Full minimal repro: https://github.com/MLoughry/typescript-repro

See src/a/lib/index.ts

// If another file in the project already has an import from the other project,
//   then attempting to auto-import `bar` will prompt you to import from 'obj/b/lib'
// If no other import is found within the project, no auto-import suggestions are found
console.log(bar);

Expected behavior:
Auto-import should work across project boundaries when an outDir is specified (with or without paths specified in tsconfig.json)

Actual behavior:

• If there is already a cross-project import within the project: The auto-import attempts to import from the outDir.
  
• If there is no other cross-project import within the project: No import suggestions are found.
  

Start with the linked minimal reproduction and src/a/lib/index.ts, then inspect the project-reference and tsconfig.json setup, including outDir and paths. Compare auto-import behavior when a cross-project import already exists with behavior when it does not; done means suggestions work across project boundaries without importing from the outDir.
