Fix broken test on develop related to dependencies issues

[inkhey]

Some test are broken in upstream due to the fact dependencies are not strict and breaking changes occured on multiple package,
to fix this we :

1. first need to find a working combinaison of dependencies version : Fix/201 use strict dependencies version to fix tests #202
2. in a second time, we do need to fix support for these new library version. Better dependencies handling #203, Support for upstream serpyco and apispec-serpyco #204, Support for apispec 3.+ #205, Support for upstream marshmallow #206

After some search:

• apispec v3.0+ cause the issue on named schema: https://travis-ci.org/github/algoo/hapic/jobs/694176231#L1112
• marshmallow v2 (v3 is unsupported but this is expected) get some new recent version but this doesn't seem to break anything.
• serpyco 0.18 and later break support for hapic, error is different between serpyco version, last version (1.3) get these kind of weird error :https://travis-ci.org/github/algoo/hapic/jobs/694176233#L1478 seems like serpyco has change a lot. apispec_serpyco cannot be updated to much as latest version required a recent serpyco.

The many parameter is now given in load/dump instead of giving it to the serializer's constructor.
