Don't assert on gn builds without any target.

NinjaWriter::RunAndWriteFiles() returned false but wrote a diag
to stdout instead of filling in *err. Later, RunGen() would
call `err.PrintToStdout();` when RunAndWriteFiles() returned false,
which DCHECK(has_error_)ed which failed since err wasn't set.
