Keep wrapper sequence value when containing only one final ad

[ZacharieTFR]

Description

This PR will allow to replace the sequence attribute of an Inline ad by the one of its parent wrapper. the replacement will be made only if the wrapper contains only one ad. Otherwise sequences from the unwrapped ad will be kept.

e.g,for a use case where an AdPod contain:

- Inline with sequence 1
- Inline with sequence 2
- Wrapper with sequence 3 wrapping a Inline with sequence 1

once parsed we will obtain :

- Inline sequence 1,
- Inline sequence 2,
- Inline sequence 3

In the use case where a wrapper wrap an AdPod, the wrapper sequence will be ignored.
e.g

- Wrapper sequence 3 containing:
  - Inline sequence 1,
  - Inline sequence 2,
  - Inline sequence 3

once parsed we will obtain :

- Inline sequence 1,
- Inline sequence 2,
- Inline sequence 3
