Task Editor bug when enter invalid time

[pmiklashevich]

Hello! Steps to reproduce:

• Open any demo, for example https://bryntum.com/products/schedulerpro/examples/localization/
• Then edit a task
• Update start date a few days ahead so event gets disappeared from the screen
• Then click on the start time trigger
• In the time input start typing, for example "1111", and you see the editor gets hidden, but the time popup is still visible. (Not expected behaviour)
• Then click on the time arrow down trigger and you'll see the runtime exception:
  schedulerpro.module.js?466403:53 Uncaught TypeError: Cannot destructure property 'eventStore' of 'this[bK4(...)]' as it is null.
