Staking reward not paid under certain conditions

[tinker-michaelj]

Description

The following timeline was observed:

• User created 0.0.A with zero balance, but staked to a node.
• Some days later, in UTC day n, user transferred X > 0 whole hbars to 0.0.A.
• In UTC day n + 1, user transferred all X hbar out of 0.0.A.
• On UTC day n + 2, user tried to collect pending rewards for day n + 1; but no rewards were paid.

But account 0.0.A's state in day n + 2 should have been:

• stakeAtStartOfLastRewardedPeriod=X
• stakePeriodStart=n

...so it should have been paid rewards for X whole hbar for one period (day n + 1).

Steps to reproduce

Replicate the above timeline.
