Fix error when clicking on header on default view

[adrienharnay]

Hello,

I noticed that when clicking the text in the header on default view, the handleRangeChange would be invoked with viewComponent === undefined.

I have patched the package to avoid the error logs, and am submitting this fix. Feel free to modify if needs be!

I am curious about the crash message you received. Can you copy/paste that here?

Your reviews? Apologies, I did not understand.

You should see my reviews on the 'Files Changed' tab of this PR. Basically I said "do this instead"

handleRangeChange = (date, viewComponent, view) => {
    let { onRangeChange, localizer } = this.props

    if (onRangeChange) {
      if (viewComponent?.range) {
        onRangeChange(viewComponent.range(date, { localizer }), view)
      } else {
        if (process.env.NODE_ENV !== 'production') {
          console.error('onRangeChange prop not supported for this view')
        }
      }
    }
  }

Hi, sorry for the late response. I am not sure your code review has been submitted, I cannot see it. In any case, thank you for the suggested changes, I have applied them!
