lab issue list is broken #901
Description
This seems to be fallout from the client-go port:
$ lab issue list
2025/04/03 14:44:29 ERROR: issue_list.go:124: issueAssigneeID (%!s(*gitlab.AssigneeIDValue=<nil>)) cannot be converted to int
$ lab issue list --assignee any
2025/04/03 14:44:49 ERROR: issue_list.go:124: issueAssigneeID (&{Any}) cannot be converted to int
$ lab issue list --assignee none
2025/04/03 14:44:54 ERROR: issue_list.go:124: issueAssigneeID (&{None}) cannot be converted to int
$ lab issue list --assignee fmuellner
2025/04/03 14:44:59 ERROR: issue_list.go:124: issueAssigneeID (&{%!s(int=31)}) cannot be converted to intI'm afraid I wasn't able to figure out how to get from the Assignee object to the numerical ID myself, so I'm opening an issue rather than a merge request.
