SwViewShell::ImplEndAction: avoid direct paint

Commit 56dd27d9 (sw: invalidate after
keypresses when we have a callback, 2015-01-13) only enabled
invalidate-then-paint for the tiled rendering case, because the main
loop had no priorities back then.

This limitation went away with 48c2815d
(tdf#91727 - Unwind non-dispatch of idle handlers., 2015-06-10), so it's
not a problem to always do this panting inside the Paint() call.
