MINOR: debug: move the "recover now" warn message after the optional notes

At the end of the too long processing warning added by commit 0950778
("MINOR: debug: add a function to dump a stuck thread"), there can be some
optional notes about lua and memory trimming. However it's a bit awkward
that they appear after the "trying to recover now" message. Let's just move
that message after the notes.
