[24.0] Fix workflow run form failing on certain histories

[mvdbeek]

If we don't replace connected values with concrete value in the run form we won't run into errors when trying to use datasets in the history as potential inputs to input parameters that are already connected. This doesn't seem necessary, and makes the run form behave more like workflow scheduling. Should fix various 500 errors that are possible if there are failed or otherwise unexpected datasets in a history.

Fixes https://sentry.galaxyproject.org/share/issue/b162b010af894eecafdaea3ae1fd8e19/:

I think this is ready and should make the run form more robust in many situations ... I think workflows with defined inputs should now not be failing to render the run form even if there's "weird" datasets in the history.
