Randomly cloning default branch instead of inherited branch from parent repo

[seb-elico]

By default, if no branch is specified for a repo in oca_dependencies.txt, the branch of the parent repo should be used (or the default branch of the repo if there's no parent repo).

For instance, when cloning account-financial-reporting 10.0, the following repos will be cloned:

• account-financial-reporting 10.0
• account-financial-tools 10.0
• connector 10.0
• queue 10.0
• reporting-engine 10.0
• server-tools 10.0
• web 10.0

However, it can happen that the default branch of a child repo would be cloned, for instance reporting-engine 11.0.

It seems like the root cause was a network issue during cloning, which has triggered a "retry" of the clone. Below is the log of when that happenned for reference:
