communi: Fix running of {pre,post}Configure

Commit 0055c6a introduced a new preConfigure hook that sets the right
qmake path. Unfortunately the mkDerivation attributes of communi
override the whole configurePhase, so this hook isn't run at all.

This fixes the build of communi and it now successfully compiles on my
machine.
