Subject: [PATCH] Fix reset treesit--explorer-last-node when explorer buffer
 was killed

Bug: After `treesit-explorer-mode` is enabled in a buffer and its
associated `treesit--explorer-buffer` is killed, a subsequent call
to `treesit-explorer-mode` initially displays an empty explorer
buffer b/c `treesit--explorer-refresh` sees old value for
`treesit--explorer-last-node`.

* lisp/treesit.el (treesit-explorer-mode): reset
`treesit--explorer-last-node` when `treesit--explorer-buffer` was killed
