Swapper doesn't allow input of "." in certain scenarios

[0xean]

Overview

If you attempt to enter a number that leads with a decimal in the swapper ".15" for example when there is already a value in the modal, it instead enters a "0" when you have pressed "." instead.

References and additional details

Steps to repro:

1. Enter a value into the swapper input (0.15 for example)
2. obtain a quote for that amount in
3. click the input amount highlighting the input amount and attempt to enter ".16", instead you will end up with 016 and then 16
