fix(server/gui): 'FXServer/unknown' in console title

At one point, the `gamename` variable moved to the fallback console
context, which made the code here only ever show 'unknown' instead of an
actual game name (like 'FXServer/gta5').

As a fix, we will look this up in the fallback console context as well.
