Merge lp://staging/~wallyworld/launchpad/recipe-build-filter-fix into lp://staging/launchpad

[r=thumper][ui=none][bug=690639] Remove the distribution from the listing and fix the filter widget in the case there are no records returned.

= Summary =

There are 2 issues with the recent recipe build page:
1. the distribution is listed for each record but at the moment it's always Ubuntu (the distribution should be removed)
2. when the filter widget is used and there are no records, the widget disappears (it should remain)

= Implementation =

Issue 1 - remove the distribution rendering from the page template
Issue 2 - move the "no records" <div> in the page template file so the filter control is always rendered

= Tests =

test -vvt test_recipebuildlisting

Added a new test - test_recentbuild_filter_with_no_records - to check the condition that broke the filter control
