fix(vendor-finance): fix lender positions after migration

[Clonescody]

Description

Following the migration to the new template, one part of the integration was failing.
A vendor pool consist of :

• 2 tokens
• One lender who only lends out === 1 token in the ContractPosition
• Borrowers who deposit + borrow === 2 tokens in the ContractPosition

The "lent out" and "borrowed" token is the same, and has to be present with two different status SUPPLIED and BORROWED.

For example a wETH/USDC pool where you can borrow USDC against wETH

If the user querying is the lender ( pool creator/deployer ), the returned balances array is

[
  "0", => wETH deposited
  "0", => USDC borrowed
  lentOutBalance => USDC lent out
]

If he is a borrower

[
  depositedBalance, => wETH deposited
  borrowedBalance, => USDC borrowed
  "0" => USDC lent out
]
