Deposit function is taking more assets than needed for the corresponding amount of shares

[miguelmtz]

It is possible for the deposit function to pull more assets from the user than needed for the same amount of shares because of rounding issues.
The amount of shares are being calculated on the line 530, but due to rounding issues (previewDeposit is rounding down), the function could make use of more assets than needed.
