SI-8479 Fix constructor default args under scaladoc
The `DocDef` node hid the `DefDef` constructor from the scrutinee
of the namer when determining if the class had constructor defaults
or not.
The current pattern for fixing these bugs is to delegate the check
to `TreeInfo`, and account for the wrapper `DocDef` node. I've
followed that pattern, but expressed my feelings about this approach
in a TODO comment.
Before this patch, the enclosed test failed with:
error: not enough arguments for constructor SparkContext: (master: String, appName: String)SparkContext
