[analyzer] Move test case to existing test file and remove duplicated test file.

Browse source 
Summary: Move the test case to existing test file. Remove test file as duplicated. The file was mistakenly added due to concerns of a hidden bug (see https://reviews.llvm.org/D104381). After it turned out, that the bug was already fixed with another revision (https://reviews.llvm.org/D85817) and corresponding test was added as well, we can remove this file.

Differential Revision: https://reviews.llvm.org/D106152
