Upgrade priority: High

Bug fix

This release includes an updated version of polkadot-js that should fix issues with decoding events on Sidecar instances that have made historic queries across runtime versions. (fixes: #290, possibly helps: #253, the fix itself: polkadot-js/api#2621)

API updates:

• (May be breaking for some users)/blocks response update: Unsigned extrinsics and inherents will have null for nonce and tip, while
  paysFee will always be false. Previously the latter two fields were 0, while
  paysFee was often true. (#274)
• New endpoint: /pallets/{palletId}/storage/{storageItemId} (#278)
