Pioneer upgrade: Upgrading and re-enabling joy-media #1048
Description
joy-media is among the biggest joy- packages and looks like it may be heavily affected by the coming upgrades. It requires more setup that other packages in order to be tested (which has been fortunately very simplified before the Nicaea release) and is partially dependent on other external tools (like versioned-store-js). It also relies on a particular mechanism of encoding and decoding entities to/from Codec types described in #1047, which will be affteted by the upgrade of @joystream/types that will cause the need for some additional adjustments.
