import/named: wildcard export not working?

Simplified version:
a.js:
```
export const a = 5
```
b.js:
```
export * from './a'
```
c.js:
```
import {a} from './b'
```
c.js errors with `import/named: export a not found in b.js`

however, when I try this simplified version, there is no error for c but it also doesn't error if I import `x` which definitely doesn't exist. So not sure what is going on…

Start with the a.js, b.js, and c.js reproductions and the import/named rule behavior described in the issue. Run both simplified examples through ESLint, then inspect how wildcard exports are handled. Done means the valid import of a is accepted while an import of nonexistent x is reported consistently.
