[TASK] Update codeception to latest patch level

composer update codeception/codeception --with-dependencies

Updates codeception from 2.4.1 to 2.4.4 and brings
phpunit 7.1.4 to 7.1.5 along with some deeper dependencies.
The younger phpunit bundle seems to be a bit more picky on
string assertions, so we need to fix two unit tests that
silently used the bug before.

Resolves: #85623
Releases: master
