bug(pull): if a dataset that is being pulled is also selected, re-fetch the log

[ramfox]

1. If you are on the dataset's page after the dataset you are pulling has finished, we need to retrigger the log to fetch, so that the dataset is reflecting the most up-to-date log.
2. pasting in a valid dataset reference that was copied from cloud incorrectly comes up as invalid in the pull dataset modal
3. We need to change that “warning” symbol in the toast that appear when you hit Pull
