Use recently used location for Extract-to dialog

With this change the path in the Extract-to dialog is taken from the last used location. It is useful if the user wants to extract multiple archives to the same folder placed deep in the filesystem tree. Works as expected with engrampa and ark. File-roller has a bit different behavior since it writes the last used archive path to GtkRecent instead of the extracted path, so the path is not reloaded by the next Extract-to dialog call.
