This reverts commit 366c5b79b1c1de0efec3b2c6a27f255b96834f9b.

BUG=XWALK-2009
Merge pull request #335 from izaman/master

Implementation of Tizen SSO APIs
[Application] Fix cannot get application info from pkgmgr db.

Since xwalk already storage [tizen_app_id] and [package_id] of wgt
to pkgmgr db, so that we cannot get application info from pkgmgr db
by [app_id].

And xwalk will send [tizen_app_id] to extensions, so that we can
get [package_id] from [tizen_app_id] and get application info from
pkgmgr db according to the [package_id].

[Alarm] Initialize the "id" to null in constructor
The alarm id becomes valid only when it's added into tizen system.
Before that we should ensure the property is enumerable.
Set the configurable to true because we can re-define the property later in sub class when it's added into tizen system.
