Merge lp:~aaronp/software-center/fix-794060-for-4.0 into lp:software-center/4.0

[Aaron Peachey]

Fixes lp:#794060 which was resulting in review duplication after a review activity (e.g. submit usefulness) as pagination code introduced in 4.0.3 no longer clears the reviews in the app details view before reloading them.

Once (and if) this branch is approved, I'll re-write the fix separately for trunk too (since the refactoring has changed alot of the structure in trunk since 4.0).

Indeed, thanks a lot for this! This is a good catch. I merged it now
and will push it to proposed next.

Thanks,
