Fix recently used packages query in app ops history

AppOpsService collects packages which have used runtime
ops recently, some of the rarely used packages are selected
for stacktrace collection during noteOp calls.

XML implementation used to read this information from
aggregated ops files. SQLite is adding an optimized
query to read recently used package names.

Use IO handler to prepare rarely used pacakges list
for stacktrace collection.
