Revert "Fix regression in PeopleSpaceActivity benchmark"

This reverts commit f1373743.

Reason for revert: b/350179642

Fixes: 350179642
Bug: 345131883

The CL fixed a strange memory issue, but also reverted a
performance improvement. We'll live with the memory
regression for the general performance benefit that not
getting the targetSdk has.
