Bug 1457709: We only do this when the command comes
from an Index object itself, which means that all the
data in the bulk request will have the same index anyway.

You'll still need to set rest.action.multi.allow_explicit_index:false
in your config.yml, or else the data will be able to override the
index name in the URL.
