* DRY up membership selector
Selectors should be chained up, not copy/pasted.
* PremiumBadge: retrieve membership db internally instead of from parent
## Ticket
1753 odyseeMembershipByUri function causing unnecessary renders
## Issue
While the rendering issue in the ticket is due to the way the props are defined, it also surfaced a prop-drilling issue with PremiumBadge.
Instead of asking the parent for the membership db, it can retrieve from Redux itself. This prevents the prop from polluting 2 levels of components and causing unnecessary renders.
## Approach
- Make `PremiumBadge` accept `uri` like most other components.
- I still leave the `membership` prop as (i.e. parent can still pass it directly). In some cases (e.g. `livestreamComment`, `page/odyseeMembership`), the parent itself needs the same data, so we don't need to derive it twice.
- Memo not required. `resolvingUris` is very dynamic and is a short array anyways.
- Changeg from using `indexOf` to `includes`, which is more concise.
