"Scanner offline/online" voice messages can trigger when XM total is low but not empty

Ravarii

*Description of the issue*

Recharging a portal as much as one's XM storage allows, using a power cube, and recharging the portal again can trigger "scanner offline" and "scanner online" voice messages as if one had dropped to 0 at some point in that process. This behavior has actually existed for quite some time, but a scanner with only a few hundred XM should still be considered functional and not cause this behavior -- actions as cheap as 50 XM are still possible.
