Denying cookies crashes the script

[jehna]

If your browser has cookies disabled, using localStorage throws an error that crashes ga-lite.

ga-lite should be able to work even without localstorage.

According to MDN:

Safari Mobile's Private Browsing mode also prevents writing to localStorage entirely.

So we should be able to skip localStorage and degrade backwards without crashing.

I am having this issue with an anonymous browser (Windows 7 / Chrome 72.0.3626). It's rare but just occurred on our production site.

This probably can be quick fixed if we add a try-catch to get-user-id.js and fall back to something that does not require a persistence (like a normal variable).

[jehna]

Though denying cookies is a strong indicator that the user does not want to be tracked; I'm thinking if we should disable the ga-lite tracking then altogether?

I have no issue with doing that... It seems like a rare case anyway.
