Fix formatExportName for single names

[franciscomorais]

Summary

This PR fixes the formatExportName for single names. For example, for names like foo it should export Foo name instead foo as named export in index.js file. This will fix the named exports in index.js.

Actual output:

export { default as foo } from './foo'
export { default as bar } from './bar'
export { default as FooBar } from './foo-bar'

Expected output:

export { default as Foo } from './foo'
export { default as Bar } from './bar'
export { default as FooBar } from './foo-bar'

The PR is motivated by this issue: #481
