`tidySCE`: `slice` masks tidyverse::slice

[stemangiola]

@HelenaLC in one occasion loading first tidyverse and tidySingleCellExperiment second, I get

The following objects are masked from ‘package:dplyr’:

    collapse, desc, slice

Specifically slice seems to be the only method that overrides the generics for some reason.

When/if you have time, could you please have a quick look? Feel free to reject the invitation if you don't have throughput.

Thanks!
