this._firestoreUnbinds is undefined in Vue 2.6.0

[maletor]

When I create an immediate watcher with this.$bind I find that this._firestoreUnbinds is null.

I see that created() is called from the mixin first but for some reason if (this._firestoreUnbinds[key]) { throws an error because unbinds is undefined.

By the way, binding declaratively works as intended perhaps because that code path is different and doesn't depend on this._firestoreUnbinds being defined in the same way.

Addendum: it does call $bind but it's not undefined. It makes no sense to me right now.

Hi, I don't understand what you are trying to do, a code sample would help, a repro would be even better

So one thing I can do is move this.$bind code to mounted and remove the immediate from the watcher and rebind there when it changes.

The reproduction is on an immediate watcher only. It's as if the immediate watcher is called before created.
