std.random.uniform!T(urng) when T is dchar disregards urng and always uses a
thread-local random

Demonstration:
---
void main()
{
    // The following loop is unlikely to complete without an assertion failure:
    foreach (_; 0 .. 100)
    {
        import std.random : uniform, Xorshift32;
        auto rng0 = Xorshift32(123456789);
        auto rng1 = Xorshift32(123456789);
        assert(uniform!dchar(rng0) == uniform!dchar(rng1));
    }
}
