Call ondestroy before cleanup

[Rich-Harris]

So that this.refs is still populated, etc. From this Gitter convo

Huh, seems this already happens in the expected order. @stalkerg can you provide a repro showing the bug you mentioned in Gitter (the Charts.js thing)?

[TehShrike]

A possible reproduction help: when I uncomment this line: https://github.com/TehShrike/svelte-1-25-0-array-binding-repro/blob/17e64d2b7292b824b8805b66443515cd411f11df/src/Top.html#L16 and start adding/removing elements by changing the number in the input, I observe some thrown errors.

@Rich-Harris please https://svelte.technology/repl?version=1.25.0&gist=c111d07479b9e65c9476bcb246944113
(you should watch logs and decrease number)
the main problem then you start using IF statement.

This is fixed in 1.27
