Improve intellisense for generated methods

See intersystems-community/vscode-objectscript#1687 for a possible improvement

Hi @evshvarov, I thought about this a little more and I think your suggestion is worth implementing. The rest of our intellisense for generated methods is helpful, but an end user would rarely want to go the system class that generated the method. I will try to get this in for the next release.
