LibGUI: Resize the mapping rows during sort
SortingProxyModel always expected the source model to have the same
number of rows as long as it has not been invalidated. Now that we have
granular updates, this assumption is no longer true, and we need to
resize the source/proxy_rows vectors to the new size. This is safe since
the values in the vector are overwritten right afterwards.
