Fix: Create item with tax (ItemModal) (#385)

The issue was found during an Item creation inside the Invoice,
Estimates or Recurring Invoice, the same fix that was applied into the
Item creation view, now is needed into ItemModal. The root cause is that
price + tax returns an amount as float making the database fail.
