WM: keep the current state when a blend fails to load
Previously many operations would run on file load, even if the file
did not load. Pre/post load handlers were called, timers canceled,
all undo data freed, editors exited ... etc.
Now keep the blend file in it's current state.
This simplifies updating this area of code as there is one less
possible situation to account for.
