[bug] Paused Byo-yomi game shows time as zero in some places

[benjaminpjones]

Here are what seem to be the relevant details:

• correspondence
• byoyomi
• Paused because of weekend
• player to move has no more main time

The more I look at this, the more I realize this may be intended behavior - this display seems consistent with display of "low main time"

However, I believe main time = 0 should show up more like the beginning of the first period ("7 days") than the end of main ("0.0"). This issue only manifests when the game is paused, because thats when we can land exactly on the border of main and period time.
