`doError` supported either a string or object, and so far there are no instances where the object version is used, so this enhancement should be safe to do without affecting anyone.
## Change
For the object version, support an additional `cause` parameter that will be logged but not show in the GUI.
## Issue
Closes 627 account header doesn't refresh on sign up / log in
## Changes
Looking back at "[Header] Changes, fixes and improvements (#493)", noticed that old code was looking at `has_verified_email` instead of just checking whether an email exists. So, restored original code.
This does have a side-effect of the Logout button not showing any email address underneath it immediately after sign up (with the flow cancelled). But I vaguely recall it was that way previously. A refresh cleans it up.
Perhaps another `user/me` when leaving the Sign Up page can make everything in sync, but this PR simpler to test.
* Add a setting to hide scheduled livestreams from home/following
* Add a hide button in the scheduled stream header.
* Fix typo + make sure pref is synced
## Issue
- When signing up, the "channel suggestions" page was stuck because `prefsReady` was never set as `preference_get` was never called.
- It was never called due to the optimizations to skip it when there is no difference between the local and server wallet.
## Change
- The first ever `sync/get` will result in a "no wallet" error, and there is already a `catch` to handle it. But the change in 38c13cf5 caused the `catch` to be skipped and went directly to `sync_apply` instead. Although the `catch` is also doing the same thing (`sync_apply`), it also has an additional callback to call `preference_get`.
- Fixed by ensuring this scenario ends up in the `catch` block like it was originally intended.
- We also did some optimization in the callback to skip the final `preference_get` if there is no difference in hash. But for the case of signing up, we do want to run it (so that `prefsReady` and other stuff gets initialized), so pass `hasNewData = true` to the callback.
