FIRE-34496 - additional fixes 

Previous fix was not correct. The underlying issue is that the cached `mAvatar` pointer is being invalidated and as a result crashing.
using avatarp instead avoids this and removes the awkward cached pointer. Might need to review if the previous reason for mAvatar reappears.
