[bugfix] Fix up error getting account avatar/header errors, other small fixes (#1496)
* start fiddling with media + account queries a little

* initialize state when pruning

* allow for unsetting remote media
make sure to wait til media loaded
fix silly tiny bug

* move comment a bit for readability

* slight reformat of fetchRemoteAccount{Avatar,Header}

* fix issue after rebase

* slightly neaten up logic of avatar/header media handling

* remove log prefix (callername log field handles this)
