In the spirit of the work done in the Library as well as the fact we open with no content in place of an empty AnchorPane I suggest we update the IssueTracking sample accordingly.
This impacts the Getting Started as well.
In IssueTrackingLite the AnchorPane hosting the ListView on the left is of no use; same for the top right one hosting the TableView. Only the one in bottom right corner is useful.
Of course this means the gesture to construct the sample deserves a rework: one can now go with the empty flavor of SplitPane and add the missing AnchorPane only when necessary.
