Remove hardcoded references to providers and stores

[woop]

As per https://docs.google.com/document/d/1MD0aS2_hGzd1tJ7DNjE3NgEtcuekh3O06OeQ9aavylY/edit#, we need to ensure that there aren't any hardcoded references in our code to Provider or Store implementations.

@woop just to be clear you mean that we shouldn't be hardcoding to any specific instance of a store or a provider, right?

Yea, so for example this stands in the way of generalizing our code. It requires us to hardcode new providers. So this issue is just tracking a scan through our codebase to identify any of these hardcoded references and to remove them somehow.

This card is done.
