[sugar] Pylint regressions

[Marco Pesenti Gritti]

Courtesy of buildbot:

************* Module view.home.grid
W0611: 18: Unused import array
************* Module view.home.activitieslist
W0311:207: Bad indentation. Found 11 spaces, expected 12
W0311:209: Bad indentation. Found 11 spaces, expected 12
Done.

Please fix them, no review is necessary since they are trivial.

Thanks,
Marco
