tdf#157304 Use normalized selection indices as string indices

The start index of the selection can be larger than the
end index.
Take that into account when using these indices to
calculate the index and character count to copy
the relevant substring using `OUString::copy`.

Without this, running the tdf#157304 macro would trigger
an assert due to invalid indices being used.

Backtrace:
