create_aliases never used when --ui is used

[albertz]

I'm not sure I'm missing it, but when looking through the code, it seems when using --ui, the aliases are not updated automatically? (create_aliases is not called automatically at startup, like it is normally the case.)

(Btw, what is the state with --ui?)

(I guess this issue here is not really urgent.)

--ui was my attempt to add a more interactive interface to sisyphus. Personally I didn't use it in the end as much as I thought I would. I'm not sure if anybody else is still using it.
