Add all expid_dir_path functions to autosubmit.py and fix tests

All previous definitions all expid_path, tmp_path, log_path and
aslogs_path (and similar) have been removed and their calls have been
switched for BasicConfig.foo() calls. Impacted tests are mainly affected
in terms of adding Mock objects since BasicConfig.foo() functions are
not available in autosubmitconfigparser yet. No new tests added
