[Paywall] Fix restoreStarted not being called on `presentPaywallIfNee…

…ded` when using `requiredEntitlementIdentifier` (#4223)

### Motivation

`restoreStarted` callback was not being fired on
`presentPaywallIfNeeded` when using `requiredEntitlementIdentifier`

### Description

We weren't doing anything with the `restoreStarted` argument 🤦‍♂️ Now
its getting passed along and gets called 💪

**BONUS:** Fixed two more that were missing in the footer (thanks
@jamesrb1 🙌 )

⚠️ We don't _really_ have a great way to test this right now 😬 All of
our existing tests use the call some internal things so we can pass
mocked customer info and intro eligibility checkers. So this didn't get
caught earlier because its one level above those internal methods that
do most of the testing.
