Calculator: Finish operation-in-progress only on new binary operations

Browse source 
Because of this the unary operations got applied to the result of the
operation-in-progress instead of the current argument as shown here:

    `16 + 9 <sqrt> =`
        Previous output: `sqrt(16 + 9)` = `5`
        Expected output: `16 + sqrt(9)` = `19`
