Watch simulator causes the script to fail

[allen-zeng]

When I try to run the script, it fails halfway:

error: No such file or directory @ rb_file_s_stat - /Users/Allen/Library/Developer/CoreSimulator/Devices/93AB1518-A3FC-4753-AA2C-419B8D39E856/data/Library/Keychains/TrustStore.sqlite3. Use --trace to view backtrace

There is a file called device_set.plist under ~/Developer/CoreSimulator/Devices/, which describes what these devices are, and the ID of the failed device falls under com.apple.CoreSimulator.SimRuntime.watchOS-2-2. It would appear that watchOS doesn't have a TrustStore.sqlite3 file. I'm not sure whether it needs it (I don't know much about watchOS).

It would be awesome if the script excluded the device paths that correspond to non-iOS devices.
