PoLine search querying non-existing poLine.acqUnitIds

Purpose/Overview:

With simple order line queries such as

/orders/order-lines?query=paymentStatus==Open

mod-orders will try to use poLine.acqUnitIds, which does not exist.

This warning will be visible in mod-orders-storage:

WARNING: Doing LIKE search without index for po_line.jsonb->>'acqUnitIds', CQL >>> SQL: acqUnitId
{{ s <> [] >>> lower(f_unaccent(po_line.jsonb->>'acqUnitIds')) NOT LIKE lower(f_unaccent('[]'))}}

The issue is in AcquisitionsUnitsService#buildAcqUnitsCqlExprToSearchRecords. The tableAlias argument is not used when an empty list of ids is retrieved.

The issue was introduced in Juniper by MODORDERS-504.

Consequences of the issue:

• All matching order lines are returned for a query of a user who is not associated with any acquisition unit, even order lines of an order with an acquisition unit.
• Potential slowdown of all order line queries

Requirements/Scope:

Fix buildAcqUnitsCqlExprToSearchRecords.

Approach:

Include tableAlias into NO_ACQ_UNIT_ASSIGNED_CQL.

Acceptance criteria:

Check that a user who is not allowed to see an order line because of acquisition units is indeed not seeing it when doing a query for po lines. Also make sure no warning is visible in mod-orders-storage after fixing.
