Fix duration of replays corrupted because of JVM/OS crash

Browse Source 
A JVM or OS crash can lead to incomplete packets at the end of a recording.
The duration of a corrupted replay file is not restored properly if that file
contains an incomplete packet. Furthermore, the entity tracker does not load
properly with such an incomplete packet. Both bugs are fixed with this commit.

To fix these bugs for replays that have already been recovered, simply open
them in the Replay Viewer, modify them somehow (save a new path) and force
the game to quit forcefully. The replays will be recovered the next time the
game starts and both bugs will be fixed.
