BUG/MEDIUM: stick-tables: complete the latest fix about store-responses

The commit 37e340c (BUG/MEDIUM: stick: completely remove the unused flag
from the store entries) was incomplete. We also need to ensure that only
the first store-response for a table is applied and that it may coexist
with a possible store-request that was already done on this table.

This patch with the previous one should be backported to 1.4.
