It has been detected that the flatten_dependencies_array() was fragile and leading to wrong results when some incorrect data was passed to it. This includes: - Missing elements. - Null dependencies. - Non array dependencies. While the existing behaviour (testing-wise) has been preserved, now the situations above are better controlled and the function ignores all those incorrect cases that shouldn't happen ever. That implies that a good number of notices/warnings/errors aren't happening anymore. That was impacting both results (when the problems were only notices and warnings) and execution (when the problems were errors). Covered with tests.
