registers: Use saved values for clipboard providers which can't read
This fixes reading from the clipboard when using the termcode provider.
Reading isn't implemented for the termcode provider so `get_contents`
returns `ClipboardError::ReadingNotSupported`. `read_from_clipboard`
needs to recognize this case and use the saved values instead of
emitting an error log and returning nothing.
Follow-up of #10839
