Fix for drag and drop issue which loads the wrong types..

[magp3]

To reproduce: Create folder a and apply one applicable type then create another folder b with only one applicable type(different from folder a). Upload a file in folder a and navigate to folder b and using drag and drop upload a file in folder b. The metadata form displayed shows the right type but the form is wrong. It shows the form for the applicable type set for folder a.

Interesting PR, thank you. Maybe it would also fix issue #133 if it's the same problem that you describe.

I tried it but it does not fix #133
