f0cd1592 did an additional call instead of replacement.
Aside: the 1 hour value only has effect in dev instances. For prod, CloudFlare seems to override that to 4 hours.
## 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.
## Issue
- Closes 592 Force clear stuck upload
- It was possible for an upload to stay "locked" e.g. when browser is killed.
## Change
When refreshing or opening a new tab, always clear the locks. The on-going sessions will re-lock them immediately.
## Issue
"No notifications" briefly appear when your previous filter is not "All".
## Change
When splitting up the category-fetch, the render logic was not updated accordingly.
## Issue
In the original Desktop code, new strings encountered during runtime will be automatically added to the local `app-strings.json` file. The feature is unavailable in Web because writing to file would require explicit permissions.
## Change
Partially restore the functionality by saving the strings to memory and retrieving it from the console via `copy(window.new_strings)`. It's a little bit of manual work, but I think it is good as it forces a sanity check before committing (previously, experimental/developmental strings are committed and being translated in Transifex).
