Issue #72: Don't explode with "Inconsistent hierarchy"
script explodes with "Inconsistent hierarchy" when reloading the module
Between the two steps we are reimporting the module, this step can explode with the following error (for "some" reasons)
Inconsistent hierarchy during C3 merge of class 'Koha::REST::V1::ERM::EHoldings::Resources::Local': current merge results [ Koha::REST::V1::ERM::EHoldings::Resources::Local, ] merging failed on 'Mojolicious::Controller' at /kohadevbox/qa-test-tools/koha-qa.pl line 112.
The script should not explode, and finish gracefully anyway.
