Fix edit channel white screen due to invalid date

Summary

The issue was caused because we were creating a date from an undefined value.

I fixed the issue and added an error boundary wrapping the input component, so if anything in that component fails the error will not affect the parent.

Steps to test

Open your channel and tap "edit", the screen should not crash

Estimated Regression Scope

None
