Price verificator

In sell modal when we try to set the price of a owned Nft, if the price has not been setted, the amount displayed in price fields is :
`0.0`

but if we want to set price to `0.0001` for exemple, we can't write it. It's impossible to tap new "0" caracters
We have to begin to write `0.01`, and after we can write other "0" between the dot and the "1"
