Manual ttaaefs causes manager to crash when scope=disabled

[stephenwood24-nhs]

On a node where ttaaefs_scope = disabled, attempting the following via remote_console;

riak_client:ttaaefs_fullsync(all_check).

causes the riak_kv_ttaaefs_manager to crash and restart, and the above command to hang.

This should be handled gracefully.
