"Share Notebook" with incompatible settings causes selected notebook to go to depth-0

[Daeraxa]

Attempting to use share notebook dialog with either an inappropriate sync target or (for Joplin Cloud/Server) incorrect credentials causes the selected notebook to lose its depth and parent notebook setting.
Before share button:

After:

Environment

Joplin version: 2.4.4 pre-release & 2.3.5
Platform: Windows & macOS
OS specifics: 10 & 11.5.2

Steps to reproduce

1. Sync target != Joplin Cloud or Joplin Server OR sync target = Joplin Cloud/Server with blank or invalid credentials
2. Select a notebook at depth >0
3. ctrl + shift + p to open command palette (or via toolbar)
4. type "share" and select "Share notebook... (showShareFolderDialog)
5. Ensure that "Synchronizing" is not shown below recipient box (wait for it to disappear if it is)
6. Hit "share", orange banner with error "Unknown key: sync.7.username" (NextCloud selected as sync)
7. Selected notebook has gone to depth 0 and is no longer with the original parent notebook

Describe what you expected to happen

For sync targets other than Joplin Cloud or Server - this dialog should not be accessible at all (along with Publish note)
For Joplin Cloud/Server sync targets - it should not be able to change the depth of the selected book due to credentials error
