Fix: src.text.details: use write_uint_prop_value to handle unsigned values in write_int_range

I tried creating an option field class with unsigned integer selector,
with a [1, UINT64_MAX] range.  The details field class shows it as:

     opt_with_uint_sel: Option (unsigned integer selector) (Selector field location [Event payload: uint_selector]):
      Selector ranges: [1, -1]

The -1 is wrong.  Fix two spots to call write_uint_prop_value instead of
write_int_prop_value.

After:

    opt_with_uint_sel: Option (unsigned integer selector) (Selector field location [Event payload: uint_selector]):
       Selector ranges: [1, 18,446,744,073,709,551,615]
