[Service] Provide webapis.isRunningApp() API

Conventionally, to know an app if it is alive with webapis, it should
get all alive packages info and check if the subject app ID is included
on them. This is very inefficient way.

So, WRT did provide below API recently.
 - wrt.isRunningApp(appId: string): bool

This patch will webapis.isRunningApp(appId: strig) also for the service
apps.
