[mobile] cannot delete categories in favorites

Reproduction steps

go to the favorites tab/pseudoguild
create a category
long press on it, to open the menu where you typically can delete channels/categories

Expected behaviour

there should be a delete button, just like when you do the same thing in an actual guild you own

Actual behaviour

there's no delete button. the channel category is permanently there. you get the same context menu as the dots on the corner? for that matter, i don't think I can rename or reorder these categories either (but both of those actions can be emulated with deletions and recreations)
