Jochen Nitschke c5e4534808 remove nullptr checks on STL search result iterators
results are in the range of first_iterator to last_iterator.
If one of those is nullptr the algorithm would fail anyway.

This removes some impossible checks in
sw/source/core/unocore/unochart.cxx:
SwChartDataProvider::detectArguments.
A sorted range still holds the same values and has
the same length as the original range.
Replacing raw pointers eases reading this code.
