CppEditor: Clean up followsymbol_switchmethoddecldef_test.cpp

with respect to test_FollowSymbolUnderCursor_virtualFunctionCall*
functions:

 - Use same function names in test code
 - Shorten test code
 - Mimic GenericProposalWidget::showProposal() calls more completely
   VirtualFunctionTestAssistProvider::itemList()
