Empty MethodCalls on Some Scenarios

[timmyteo]

When running Dosai with the Dosai source code as the inspection input, the resulting output JSON has an empty array of objects for the property MethodCalls. This is unexpected and it seems that because of the way the code is written, that Roslyn is throwing an error (see attached screenshot). The goal of this issue is to potentially identify the bug and fix it so that the MethodCalls populates when inspecting the Dosai code.
