tensorboard does not find profile, if logdir directs to a parent directory

[eyaler]

usually we can direct tensorboard to a parent directory to see multiple models. however, tensorboard does not find the profiling data (by capture_tpu_profile), if logdir directs to a parent directory

Nice suggestion. Will send a PR to fix this. Hi @nfelt, can you assign the issue to me?

@qiuminxu Hmmm I tried but I'm not able to pick out your github handle in the issue dropdown box, I think it's because you're not a member of the Tensorflow github org. I'll follow up internally.

This should already have been fixed by the following PR:
