updateField doesn't support broken paths

[fusionbeam]

I have to map an object with a two level depth of nested dynamic properties.
i.e. myContainer.$category.$name.value

I am calling commit('updateField', {path:myContainer.${category}.${name}, value:metric.value});
If $category has never been set separately this break with an error 'Cannot set property ... of null'.

This should be an easy fix, to ensure path safety by creating empty objects if the key doesn't exist already.

Hey @fusionbeam! This seems to be the same as #41 (I know, the title is a bit misleading I guess)

Pull requests are welcome!

I'll close this issue, please use #41 for further discussion of the topic.

Please let me know if I miss understood your problem and I'll reopen this. Thanks!

@maoberlehner technically this is different but I can see how working on a fix for #41 can include a fix for this use case as well.
I'm working on a pull request.
