When Importing an stl file into Godot from the import mesh menu, the editor hangs indefinitely. Since only Obj files are supported, the data remains unparsed and hence the editor enters an infinte loop. This commit fixes this issue by exiting the loop when godot has finished parsing the file, irrespective of whether any meaningful data was extracted out. Fixes: #9200
