Fix an override_module bug.

Browse source 
proptools.PrependProperties doesn't replace a pointer when both the src
and the dst have one. This prevented override_module from overriding
simple value pointer properties when the base module has existing
values. It turns out this was why the name property needed to be
overwritten manually.

Bug: 122957760
Test: app_test.go
