_The documentation is not available anymore as the PR was closed or merged._

Updated so that `infer_framework_load_model` is not called at all if `model` is already loaded and `framework` is defined.

However, it may still be worth keeping the check inside `infer_framework_load_model` so that if `framework` is defined but the `model` is a `str` and we do need to call `infer_framework_load_model`, at least we don't need to then call `infer_framework` inside of it.

Ok, this code breaks some tests. Can you fix them ?

Noticed a "typo", it is fixed now.

@denis-ismailaj it's ready to merge !
