fix: #7448
Current we skip on those experiments which already existed on both sides, but
do not exclude them from the result list. And if we have diverged experiment,
pulling/pushing them will stop the current progress and raise an exception, but
didn't give any information on the condition of other experiments.
1. Change the exp pull and push to match the new API in `scmrepo`.
2. Handle sync status after `exp pull/push` finished.
3. Bump scmrepo to 0.0.19
