Calling setActiveStake for a staker resets the wait time even if no balance was moved

[sisou]

When a staker that has 0 active balance sends a setActiveStake transaction that sets the active balance to 0, no balance is moved but the inactiveFrom block is still reset to the next election block, resetting the inactivation wait timer.

Sounds like reasonable behavior to not special-case this. Does any problem result from this behavior? If the staker sends such a transaction despite not needing it, that's on themselves IMO.
