[NuGet] Fix column header now read for first column in Consolidate tab

Combine project name and check box in Consolidate tab. This fixes the
problem where the check box has a column with no name. Now the check
box and the project name are in the same column so Voice Over reads
the column header name, the project name and the checkbox state which
makes it easier to understand what the list view is displaying.

Fixes VSTS #1021702 - Accessibility: NuGet Packages: Column Header
name is not present for the first column.
