### Purpose
There were some additional regression created during #10563 and #10631 which are:
* Folders were not being ordered by their label within their group
* Local device could still show up randomly with the list of remote devices
The respective fixes in this PR does the following:
* Ensure sorting of the grouped folders (and devices) are done by group name (the top level map key) and then by the specified nested object property or a fallback property if specified property value is empty. So in the case of the folders it's `label` and device is `name`.
* When populating the `devicesGrouped` using `$scope.otherDevices`, do this within a watcher on `$scope.myID` as this is what `$scope.otherDevices` relies on to determine what is a remote device. This is required because `$scope.myID` might not be populated yet given the indeterministic call order being made to `refreshSystem` and `refreshConfig`.
### Testing
Populate folders and devices into different groups, and ensure the ordering is correct and the local device is not showing in remote devices even after many, many refreshes on the UI or restarts of syncthing entirely.
