Fixes NB#63571
Changed the name modest_platform_connect_and_perform_if_network_folderstore(..), that now is modest_platform_connect_if_remote_and_perform(..).
Removed modest_platform_connect_and_perform_if_network_account, because the above function performs the same task.
Changed modest_ui_actions_create_folder to use the asynchronous call modest_platform_connect_if_remote_and_perform(..).
Added a call to gtk_tree_model_filter_refilter(tree_model) by the end of on_row_inserted_maybe_select_folder(..) in modest-folder-view.c, so the folder with the new name is shown.
