Fix missing primary_key in haeckel theme custom SQL execution

Automatically generated queries start with the primary_key field
which is linked to edit a row. The haeckel theme changes this link
into an edit icon, and there's no problem since adminer will
automatically select the primary_key a second time.

In custom SQL queries however this second field selection can't be
inserted and the primary_key is eaten by the icon, making it hard
to find a row by id.
