Check for duplicate house not extensive enough

[Tanzhiheng26]

Steps to reproduce

• addSeller n/John1 p/98765432 e/johnd@example.com type/Hdb street/Clementi Ave 2 blk/311 level/02 unitNo/25 postal/578578 price/999999999
• addSeller n/John2 p/98765432 e/johnd@example.com type/Hdb street/Clementi Ave 2 blk/311 level/2 unitNo/25 postal/578578 price/999999999

The leading 0 for the level makes the 2 houses different but they are the same.
