Drop throw clause that was incomplete anyway

SvxUnoTextRangeBase::SetPropertyValueHelper throws a
css::lang::IllegalArgumentException but its delaration did not mention
that. This caused a crash in sd_filters_test with Apple's Clang which
does not have -fno-enforce-eh-specs. So drop the whole throw clause.
