Fix a side channel leakage for the pm#getLaunchIntentSenderForPackage

am#isIntentSenderTargetedToPackage returns false if the target intent
data has a non-null package name and a non-null component name. This
condition hits the successful case of the
pm#getLaunchIntentSenderForPackage api, and the application can
detect package's existence information via both apis. Removes the
package name from the target intent if the lauch intent is found
for the package to fix the issue.
