Bug: Code completion incorrectly interprets arguments as part of signature

[rnicholl]

The code completion plugin is incorrectly interpreting argument names as part of the symbol:

e.g.

Code Select Expand

class A
{
  void write(std::byte const * foo, size_type bar);
};

does not match:

Code Select Expand

void A::write(std::byte const * fizz, size_type buz)
{

}

But instead provides two different symbols in the symbol browser. This behaviour is wrong, the argument names are not part of the function signature. It's perfectly legal to omit them from the declaration entirely.
