Subject: [PATCH] [Common][Package] Avoid recalling app_info_create() for
 consecutive calls

app_info_create occasionally when the device is freshly reboot takes
much time to gather data (over 1 second), which causes a serious delay
when the function is called several times in the row without caching the
result.
This modification makes a single call of app_info_create() at first try
and then only return previously fetched value.

[Verification] Code compiles without errors.
TCT application, package, deprecated - passrate didn't change.
