Related: rhbz#790233 Allow styles to be deleted from the template dialog

I knew this used to work at some stage, appears to be a
regression since cdf8680e
GetIndices_Impl gives the region and index of the entry relative to the
immediate parent, so doesn't make sense to use those as indexes
into the template array if we're at the style level.

backup into the template level if we're below it to get the
relevant template index.
