TimespanHighlight: not playing well with filter

[Jerther]

Hello!

Here's how to reproduce:

• Load the demo: https://bryntum.com/examples/gantt/highlight-time-spans/
• In the console, apply a filter:
  gantt.taskStore.filter({filters : task => task.name == "xx", replace : true});

• Then create a highlight for a task:
  gantt.highlightTimeSpan({
      taskRecord: gantt.project.taskStore.getById(1),
      name      : 'hello!',
      startDate : new Date(2019, 01, 01),
      endDate   : new Date(2019, 01, 06)
  })
  

• Crash!

Expected:

• I'd expect highlightTimeSpan() to do nothing
• If it did nothing and I then I had the task shown by changing the filter, I'd expect the highlighted timespan to be visible again.

Also, if you highlight a task timespan and THEN apply a filter so that task moves around, the timespan does not follow its task.
