Does this fall back to Chromium's IDS_EXTENSIONS_UNINSTALL when in an unbranded
build?

I changed the #include to chromium_strings.h which I believe will fix unbranded
builds; through some non-obvious magic, I think the string gets overridden in
branded builds, but going to manually check.

Acknowledged.
