fix(test): use $tracker_num parameter in dict_manager! macros instead of hardcoded 2

[viktorking7]

The dict_manager! and dict_manager_default! test macros accepted a $tracker_num parameter but ignored it when inserting trackers into the DictManager, always using a hardcoded key 2. This created a mismatch between the macro's signature and its behavior, making it incorrect for any $tracker_num != 2.

@viktorking7 thanks for contributing, please remove the test as it doesn't make sense to test a test util
