Fix the failing tests in InternalCallsTest

[bilyana-gospodinova]

Description:
Adapt the failing tests in InternalCallsTest. There is a difference in the behaviour in the mono code and the modularized code, so depending on the modularizedServices flag the test assertions are different.

Fixes #10089
