Bugfix/open galaxy export dialog
This merge request fixes the galaxy export dialog appearing when clicking on the "Export to Galaxy" button after selecting samples on a single project.
I don't know when this broke, or how it worked in the first place. Looking through the history in the last month doesn't elucidate much, the block around that area hasn't been changed since Joel wrote the code.
In this specific context, returning
false directory on
multiProject makes sense, we're selecting samples from one project to export to Galaxy.
