android: Deduplicate LOKitThread#load{,New}Document

After Change-Id I15ecc2eba6c5ee441f6e14f8229594cab05dbba7
"tdf#148556 android: Don't delay refresh when loading doc",
the only thing that `LOKitThread#loadNewDocument` does
in addition to `LOKithThread#loadDocument` is to save the
newly created document (to a temp file) if loading was
successful.

So, have `loadDocument` return a boolean saying whether
loading was successful and call that method from
`loadNewDocument` to reduce duplication.
