Fix a dyno bug preventing resolution of 'this' calls on a variable that shadows another.
The problem stemmed from looking up the identifier we call 'this' on as though it were a function. In function resolution, we look for all visible identifiers rather than just the innermost. However, for an implicit 'this' call on a var, we want to look up the (innermost) var, then call 'this' on it. Fixed by just resolving to the innermost result between an ambiguous set of variables.
Also adds testing for the fixed case, as well as that a similar case (correct ambiguity between methods in analogous scopes) isn't broken.
Resolves https://github.com/Cray/chapel-private/issues/6706.
Note to reviewer: Went though several iterations, so changes are probably easiest to review as a whole rather than by commit.
