Dropdown list is not statically updated

[mmiladi]

Consider a scenario where a wrapper/workflow is already opened and some data processing is running. For a newly generated data, it is not shown inside the dropdown list of opened wrapper input section. The user have to reopen the wrapper again to see new data in the dropdown list.

This issue is described here:
bgruening/docker-galaxy#279

However apparently it does happen for galaxy-graphclust and does not affect docker-galaxy-stable.
