Fix duplicate package name output.

Previously, when issuing `adb shell cmd transparency get module_info`,
package name may be printed twice when corresponding PackageInfos
could not be found. This change fixes this issue.

Bug: 216647433
Test: Issuing the following shell commands output the correct printout:
`adb shell cmd transparency get module_info`
`adb shell cmd transparency get module_info -v`
