Add useful development assertion
When debugging snippets after M-x toggle-debug-on-error, errors in the
`post-command-hook' might cause `yas--post-command-handler' to be
removed. That's OK, always check that it's there before attempting any
`yas-expand-snippet' calls, since it is essential to check snippet
movement.
* yasnippet.el (yas-expand-snippet): Assert `yas-minor-mode' and
`yas--post-command-handler' active.
