Delete front Connections in Database isn't working

[ijdod]

Version 21.01, reproduceable in demo.opendcim.org.

When you view a cable path through Path Connections > View Patch Connections, and select the 'Delete Front connections from database', only one (I think the bottom one) of the front end connections shown is deleted, and 'Error' is displayed on screen just above the search boxes.

Incidentally, I wouldn't mind that 'delete front connections' button being available from the device path view you get when you click on an interface.
