Codesandbox Case (Bug Reports)
Forked sandbox with instructions to recreate:
https://codesandbox.io/s/primereact-test-forked-vonjm

Current behavior

Changing the hourFormat does not refresh the displayed datetime in the calendar's input unless the date is changed.

Expected behavior

Changing the hourFormat would immediately update the display, e.g. "1:00 PM" would become "13:00"

Minimal reproduction of the problem with instructions

See link above for live demo with instructions. Minimal repro is this:

1. Display a date in the component.
2. Programattically change the timeFormat prop from "12" to "24"
   The format change is not updated in the Calendar's input unless the date changes.

Please tell us about your environment:

Windows 10, create-react-app 3.4.3, VS Code

• React version: 16.12

• PrimeReact version: 4.2.2
  This is the version we are on, and that's what I put in the sandbox.
  I could not get the sandbox working with 5.0.2 to test that version. Looking at the code, I expect this issue still exists there.

• Browser: all

• Language: ES6 (all suspected)

Note
My use case is only concerned with hourFormat. I suspect the following props to have the same behavior though, since they similarly affect the date display in the input:
dateFormat
timeOnly
showSeconds
showMillisec
