fish completion for assume only loads after granted completion is triggered.

[tmeijn]

In #645 the completion name was correctly changed to comply with the completion loading logic in fish. However, the completion for assume only loads on once granted completion has been triggered, since both completions live in the granted.fish completion file.

An easy fix would be to write the completion two times, once for granted, and the other one for assume.

Fresh terminal:

assume-completion.webm
