Can't export the derived bioassays column in physical bioassays list

Use the "Save as" feature to see the error message, otherwise export just stands waiting at 0%.

Exporting all other columns seems to work. Seems like the export was broken by the fix to #1895 which introduced the '%' in &rootDerivedBioAssays(%name) to fix the filtering issue.

Need to update the code that assigns data loader and formatter for this columns since the '%' is missing there.

(In [6715]) Fixes #1918: Can't export the derived bioassays column in physical bioassays list

Add '%' to the registration of data loader and formatter so that the names matches the filter expression.
