[CMT2][BUG]In migration, there is pk and unique index, the unique constraint will be lost.

1 Create one table

CREATE TABLE "TEST"."AGENT_GROUP1"
( "AGENT_GRP_ID" NUMBER(*,0),
"GROUP_NAME" VARCHAR2(40) NOT NULL ENABLE,
"DESCRIPTION1" VARCHAR2(100) DEFAULT NULL,
PRIMARY KEY ("AGENT_GRP_ID")
)

CREATE UNIQUE INDEX "TEST"."AGENT_GOUP_NAME1" ON "TEST"."AGENT_GROUP1" ("GROUP_NAME")

2 Do migration to offline.

Actual result
The unique index of AGENT_GOUP_NAME1 will be lost.
