rCOMMfa38e5944b38: [services] Blob - Switch from memcmp to a simple EQ in database tests
Summary

@palys-swm revealed a bug related to the use of memcmp in this case:
The test would not fail if the test item is a prefix of the found from database item, because we're comparing only
item.*someItem.size() bytes. We don't need to compare the sizes, because the switch to the simple comparison of strings solves the
problem.
