* assets: execute `died` hook outside of mutate Signed-off-by: Oliver Tale-Yazdi <oliver@tasty.limo> * assets: extend tests for `died` hook Signed-off-by: Oliver Tale-Yazdi <oliver@tasty.limo> * assets: update doc of FrozenBalance::died Signed-off-by: Oliver Tale-Yazdi <oliver@tasty.limo> * assets: review fixes - fix cases where `died` should not have been called - use `Option<DeadConsequence>` instead of `DeadConsequence` Signed-off-by: Oliver Tale-Yazdi <oliver@tasty.limo> * assets: update comment in mock.rs Signed-off-by: Oliver Tale-Yazdi <oliver@tasty.limo> * assets: return `Remove` in dead_account The return value is ignored in the only case that it is produced by a call, but having it this way makes it more understandable.
