rangePlugin causes an error when onChange contains react setState call

[SmevSmevson]

When using rangePlugin the initial inputs work as expected. When clearing the input the onChange event causes an error when it calls a react setState.
Cannot read properties of undefined (reading 'getTime')

Steps to reproduce

1. enter the start and end dates
2. select the start input
3. Press backspace key
