useMemo in useResources

For performance:

```js
import _ from 'lodash';
import ContextWrapper from './resource-context';
import { useContext } from 'react';

export default function useResources(resourceType, filter) {
const store = useContext(ContextWrapper.Context);

// Memoize this
return _.chain(store)
.get(`state.resources.${resourceType}`)
.filter(v => filter(v))
.value();
}
```

Start at the useResources hook shown in the issue and inspect how its store and filter inputs change between renders. Done means the returned filtered resources keep their current behavior while the computation is memoized for unchanged inputs; validate this with the repository's existing checks.
