Previously, when creating pose assets with the experimental baklava flag
enabled, although the asset would be created correctly as a slotted action,
and the resulting action would be assigned to the ID, the slot itself was
not assigned.
This commit updates the code to select the slot as well when the asset
is created as a slotted action.
Note that *applying* pose assets that were created this way is still
not functioning correctly, which will be addressed in a forthcoming PR.
