[Alarm] Don't raise an error when an alarm without TYPE is found
tizen.alarm.get() and tizen.alarm.getAll() used to fail when alarms
without "TYPE" property in related app_control existed.
This commit returns such alarms as JS Alarm objects.
[Verification] tct-alarm-tizen-tests (auto): 100 %
I've tested in Chrome DevTools debugger, that when an alarm without
"type" property comes to JS, a valid "Alarm" object is created
(I don't provide any test code snippet, because it required stopping
app in the debugger).
