[FIX] fix bouncing problem on create/import buttons

the bouncing is supposed to occur when clicking on the area in view list
with no content.  Problem was that the Create button was separated from
the import button while bouncing.  This commit fixes the issue in a not
really subtle way: it instead bounces the whole row.  I tried to find a
better fix, but I don't like jqueryui and i don't want to spend too much
time on this.
