This change makes the current fragment load on configuration changes for
the gesture navigation tutorial. Previously, the old fragment would be recreated causing inconsistencies when rotating the screen. Not marking a flag as this change is for both the previous gesture tutorial and the current one.
Fix: 317162126
Test: Run the tutorial and rotate the screen after each step. The
tutorial should progress like normal.
Flag: N/A
