Swap flicker on first input

[micahalcorn]

When I first load the swap form and enter an amount, I get a brief output that doesn't make sense. See this example where my input is 150 and the output is 0.99999xxxxxxxxxxxxx for a fraction of a second before changing to 150.

This delay is from typing in 1, it running the amount received, and then replacing it with 150. I can increase the debounce interval a little bit so if you are typing a bit slower it will not do this.
