FileManager: Fix TreeView collapsing on file system changes (#4348)

Browse source 
TreeViews using FileSystemModels collapse whenever the file system is
changed in anyway. This includes creating, dragging, deleting or
pasting any files/folders. This commit updates the refresh_tree_view()
lambda, which seems to have stopped working at some point, and calls it
whenever any of the actions mentioned above are activated.
