* Revert "Remove unneeded try catch in voice command funtionality (#899)"

In some case the try catch is needed. See

(only visible to the openHAB staff).
I updated the code to open the Google app in any app store. Some users
might use YALP store or any other custom Play Store (or Amazon app
store). For users without any additional app store the Play Store is opened.
