ToothFairy 2.7.3 incorrectly claims disconnected

[Michael_Tsai]

@Tommmy

After a while a dialogue box appears saying disconnected. Clicking the icon shows charging for a little while and shows connected and repeats itself
The preference pain shows connected all the time but only changes charge level after completely quitting system, preferences and launching it again

I think these issues are fixed in ToothFairy 2.8.
