Schlage Connect Touchcreen unreliable after last device hanlder update

[nbaechtold]

I recently pulled in the latest device handler update for my Schlage Connect Touchscreen. Unfortunately, the lock and unlock actions immediately became unreliable. I would initiate a command to lock or unlock and it would very often get stuck in the locking or unlocking state and never actually take any action on the lock.

In the event that it did actually take the action there was a delay of around 5-6 seconds that wasn't there previously and the locked or unlocked status would take even longer to update after the action had been taken.

Reverting to commit 93bd6dee8437a35f38912cc1714d715ef164caba immediately resolved all of these issues.

-Thanks

Any reason you wouldn't use the 'Zwave Schlage Touchscreen Lock' DTH in this repo? That was not effected by the recent change.
