Update of Slicer issue tracker

this is a report about a potential bug in qMRMLColorTableComboBox
(i think the github tracker is not yet active)

platform: windows
version: 3d slicer 4.10.2

steps to reproduce:

  1. start slicer
  2. load a scalar volume
  3. go to the volumes module
  4. ensure the loaded volume is the active volume
  5. the lookup table combobox provides a preview of all colormaps (as expected)
  6. close the scene without saving
  7. load the scalar volume again
  8. go to the volumes module
  9. ensure the loaded volume is the active volume
  10. the lookup table combobox does not provide previews of colormaps anymore
