[DateTimePicker] crashes with hooks-out-order error from React

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

When I implement a DateTimePicker that can be set to read-only (not open the dialog) or editable dynamically like it is done here, setting the open property dynamically will cause an error like this:

Warning: React has detected a change in the order of Hooks called by PickerWithState. This will lead to bugs and errors if not fixed. For more information, read the Rules of Hooks: https://fb.me/rules-of-hooks

   Previous render            Next render
   ------------------------------------------------------
1. useContext                 useContext
2. useContext                 useContext
3. useState                   useCallback
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    in PickerWithState (at App.tsx:14)
    in MuiPickersUtilsProvider (at App.tsx:40)
    in div (at App.tsx:28)
    in App (at src/index.tsx:7)

Expected Behavior 🤔

The DateTimePicker component should just be re-rendered as read-only or not. It would be great if there was a readOnly prop in the component out of the box.

Steps to Reproduce 🕹

Setup in a Sandbox here: https://codesandbox.io/embed/materialui-readonly-datepicker-klttf

Steps:

1. Click the checkbox
2. See Console Errors
3. If you want, comment out the code that “crashes” and uncomment the one that doesn’t.
4. It will work as expected in that scenario.

Alternatively, clone this repo: https://github.com/agonzalezjr/materialui-readonly-datepicker (it’s just a create-react-app ... --typescript with MaterialUI installed and App.tsx modified to reproduce the issue.

npm i
npm run start

In the main web page, click the checkbox.

You must not change open property to undefined dynamically. If you need to - please implement your own state for open prop.

Ok, that works! Thank you so much!

I have updated the sandbox with the fixed code https://codesandbox.io/s/materialui-readonly-datepicker-klttf
