Issue with linking Dataviews and XForms as media to a form

[FrankApiyo]

Environmental Information

• Onadata version: All

Problem description

Sometimes forms have the same ID as data views because they are in different DB tables.
This endpoint's parameters do not clearly distinguish between DataViews and XForm IDs; it's a bit unclear what will happen when an XForm you'd like to link to has the same ID as a dataview that you don't want to link your form to (and the converse would also be a problem)

Expected behavior

There should be a way to distinguish between XForms and DataVIews in the datavalue parameter to the metadata endpoint
