Regions cache may not be filled with all regions

[stopostit]

A customer faced an issue with the CLI, the user has been granted access to osc-secnum-fr1 but it is not not appearing in the regions cache.
The fist call to get the regions list is not displaying osc-secnum-fr1 while the second one is working as expected.

Workaround:

mv ~/.cache/scalingo/regions.json ~/.cache/scalingo/regions.json.bak
scalingo logout
scalingo login
scalingo --region osc-secnum-fr1 apps
