Remove LiveDebugger warning on production

[kraleppa]

When you install LiveDebugger from main it'll throw a warning each time when assign size is calculated. It's because we are passing LvProcess.assigns to the async function to calculate them in the background if they're heavy, and LiveView assumes that we are passing standard socket assigns because of imperfect system of detecting such cases.

The problem is that this warning is being displayed on production flooding iex with LiveDebugger warnings
