Removed updateEntityProperties's transactionality
entity.put() is already transactional, and all other methods called
do not need transactionality (even so, it is hurtfull that they are
run within a transaction).

Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
