Fix wpcom user ID being [object Object]

[kmanijak]

For some blogs, the _ui in tracks end up as [object Object]. This points to the JS code which coerce object into string. This happens only with _ut wpcom:user_id.

The user recognition happens in tracks_get_identity method and seems like in some edge cases $wpcom_user_data['ID'] is not a string. I don't know Jetpack enough so I couldn't determine what are the conditions.

Why I think it's here and not other places?

The same issue occurs in WooCommerce and if Jetpack is available it uses the Jetpack's Tracking method directly here to determine the _ut and _ui, then use it directly with no further modifications.

Ref: p4qSXL-8qM-p2#comment-24297

Proposed changes:

• I suggest adding additional check if the values are strings before using them as _ui. If not, fallback to anon
