Debugger: Set current tab in separate value display
Debugger: Set current tab in separate value display

As widgets are added and deleted from the tab widget, they can end
up in almost any order. As a result, when the window is raised, the
current tab does not necessarily reflect an item currently in the
watch view. Instead, make a tab the current one as it is added,
ensuring one of the currently relevant values is displayed by default.
