appUpdatesEnabled throws TypeError when called with null

[hsusul]

Describe the bug

In src/helpers/updateCheckPolicy.js:

appUpdatesEnabled({ notificationsEnabled, notifyUpdates } = {}) has default parameter = {}, which only triggers when the argument is undefined. When called with null or a non-object value, it throws:

TypeError: Cannot destructure property 'notificationsEnabled' of 'null' as it is null.

To Reproduce

1. Call appUpdatesEnabled(null) -> throws TypeError.

Expected Behavior

appUpdatesEnabled should safely handle null and non-object values, defaulting to true (check-by-default behavior) without throwing an error.

Closing together with #1828 — full reasoning over there. Thanks for the report, @hsusul!
