Revert "Try uninstalling Maps to get latest version from pStash instead"

This reverts commit 34202ba0.

Reason for revert: The removal cmd doesn't work in the lab (worked locally), and the installation fails as it is unable to override mismatching signature packages: "Error: INSTALL_FAILED_UPDATE_INCOMPATIBLE: Existing package com.google.android.apps.maps signatures do not match newer version; ignoring!' [38151FDHS000BZ felix:felix MAIN]"
