Issue importing doc

[podviaznikov]

When I import doc which has two array items (with a property that has null) all works fine:

const importedDoc = cambria.importDoc({
        items: [
                { name: 'Peter Johnson', nationality: null },
                // { name: 'Ashley Appleseed', nationality: null },
                { name: 'John Doe', nationality: null }
              ]
    })

but if I have 3 items in the array:

const importedDoc = cambria.importDoc({
        items: [
                { name: 'Peter Johnson', nationality: null },
                { name: 'Ashley Appleseed', nationality: null },
                { name: 'John Doe', nationality: null }
              ]
    })

it fails with error:

(node:21691) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'type' of null

Bumping above ^^^

I created a Runkit snippet where the same thing happens.

It's related to the postProcessFnc in importDoc

Comment out line 20 in src/docs.ts and recompile (yarn build) and it works.

I was able to reproduce both the problem and the mitigation. I'm not sure what that line does though, nor what the side-effects of removing it would be.
