Initial filter in watch recordings broken

[kuphal@…]

Looks like [7358] broke the initial filter for watch recordings. cancelPopup cannot be called when displaying the initial filter because there isn't a popup to be canceled which is contrary to the typical behavior when displaying this box because it is normally called from another popup. This patch fixes.
