tdf#128895 sc xmlimport: create enough dynamic cols if props

Since LO 6.3, only 64 columns are created by default,
where previously it was a fixed 1024.

A common user practice is to hide all columns not used,
but this collapsed property was lost because
only part of the columns were actually created and thus exported.

In this example, import specifies 1017 hidden columns (H-AMJ),
but since only 64 columns are created, export only specified 57.

So ensure that on import, any column with defined properties
is created - even if they don't contain any content.
