Speaking of testing, I think this sort thing would benefit from a
regression test, so I added that to the patch. I will to master push in
a few days if there are no objections.

Subject: [PATCH v2] Don't require isearch-update before isearch-done
It is useful to be able to call `isearch-done' unconditionally to
ensure a non-isearching state.
* lisp/isearch.el (isearch-done): Check that `isearch--current-buffer'
is a live buffer before using it (Bug #21091).
* test/lisp/isearch-tests.el (isearch--test-done): Test it.
