always use sanitized URI from ApkFileProvider in install process

Browse Source 
The previous commit makes this issue a lot easier to see. ApkFileProvider
getSafeUri() was already making the right URI for SDK_INT < 24, but then
this bit of logic was using the original URI, which didn't work. Installing
from the app's cache dir triggered a "Parse Error".  The Android default
installer API needs file:// URIs from getFiles().
