nit: It looks like the body of these 3 tests are identical except for how the
extension is loaded, and what the expected values of embedded_plugin &&
content_handler_plugin is. Consider refactoring the common parts into a member
function in the NaClExtensionTest class - one idea would be to have it be
something like this:

enum TestExtensionType {
  FROM_WEBSTORE,
  NOT_FROM_WEBSTORE,
  COMPONENT
}
void RunTest(TestExtensionType type, bool nacl_allowed) { ... }
