#284 Tooltip/context menu shows only the fleet and not the planet

[Jure Repinc]

Steps:
1. I just moved the fleet to a system where I destroyed aan enemy flet.
2. I moused over that system (efko) to get a quick info in the tooltip

Result:
The tooltip only shows my fleet (Razfuk), but doesn't show the planet there. I've also noticed that context menu only contains my fleet and not the planet.

Expected:
The tooltip should show my fleet and the planet. So should the context menu.
