AFAIR, the check for is_present() was done by @hirono in order to overcome an
issue with stale thumbnails when the file is modified locally but not synced
yet. I'm worried that removing it will reintroduce the regression which was
recently fixed.

+@hirono to confirm.

The generated thumbnail has higher priority and the generated one is always
shown when available. so the problem should not be occurred, I think.

         new std::string("https://www.googledrive.com/thumb/" +
                         entry_proto.resource_id() + "?width=500&height=500"));
