Sort Apps During setApps

We found this potential edge case during the creation of AllAppsSearchImageTest.
Search in all apps uses a binary search which requires the list of mApps to be sorted,
which before the function setApps did not do. This could lead to other edge cases of bugs
either in test or production.
