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.
