Ajax 404 when deleting a file inside of a tab on edit screens

[krisimmig]

We get a 404 error when trying to delete a file from a file field.

It only happens when we are using the tabs also on the edit screen with use TabsOnEdit;, else everything works fine.

It seems that there is an error in the nova/src/Http/Controllers/FieldDestroyController.php.

To reproduce:

• add a new model like "FileTest" with just one column for a file name
• add the nova model with Tabs and the file-field inside the tab
• add the use TabsOnEdit; to the nova model

Now try to upload and delete the file again from the field in nova. There should be a 404 error in the network tab of the browser debug window.

Does anybody else have the same problem?
