Fix invalid access crash on exit in LimboHSM
Since #131, `LimboState::_exit()` became a source of potential crashes
if object references are used without a validity check. It's too easy
to miss this, which can lead to game crashing during runtime.

This fix reverts #131 change and proposes alternative approach of
re-activating root HSM upon tree entering if it was previously active.
Note that it's not an ideal solution, as some state will be lost upon
re-parenting: HSM exits and then re-activates and enters its initial state.
