vscode: restore removed default values

[Veetaha]

After refactoring the config we forgot to set defaults for
some properties like workspaceLoaded, callInfo.full, etc.
This commit restored them to being turned on by defult,
as well added defaults for other props to be more explicit
on their defualt value.

I am actually not sure if we need these defaults -- they are set in the server anyway.

The benefit here is that we document the default for the users of VS Code.

The drawback is that we have to maintain a second set of defaults.

[Veetaha]

This is actually
a fix, since the defaults are implict on the vscode side. So now workspaceLoaded and callinfo.full do
n't actually work

I was surprised, but running with a debugger it is obvious, that vscode sends default falsy values according to the declared json schema. So e.g. all booleans get false values and all arrays get [] values. Thus, we have to override them explicitly on vscode side anyway...

That's unfortunate....

Don't underestimate that benefit :-)
