Thunar won't open when last view has unavailable location.

Similar to (or part of) #1022 (closed), thunar will not open if restoring last view includes an unavailable location such as a disconnected gvfs/smb share.

Version information

git Artix

Steps to reproduce

1. Make sure 'Restore tabs on startup' is enabled.
2. Navigate to a smb share.
3. Close thunar.
4. Disconnect the share.
5. Open thunar.

Current behavior

Thunar waits for a timeout on the share before displaying the window.

Expected outcome

Thunar displays the window immediately and shows a 'loading' icon to indicate that it is busy, without freezing the window
