QmlDesigner: Fix build

Browse Source 
Yes, it is possible to set a unsigend integer to -1. It is defined that
a unsigned integer is underflowing and then you get the largest integer.
With https://en.wikipedia.org/wiki/Two%27s_complement it exactly the
same bit pattern as a -1 signed integer too.

But many compiler like the mix of signed and unsigned because it can
lead to bugs. So just use the unsigned interId() data type and set the
special value to the maximal integer.
