Fixing import command no primary key issue

[gabor-boros]

Reason for the change
Restoring doesn't pick up primary_key from info files.

Description
In turned out that the primary key was parsed from the info file, but not used at table creation at all, hence the table was created with the default primary key id. The issue was introduced right after 2.3.0.post6 was released in 2016.
