Instances referencing non existing "platform_aws_m1" platform, leads to 500 error /

[bpetit]

Bug description

"platform_aws_m1" is referenced by instances .m1. in aws.csv, but this platform doesn't exist in server.csv

Querying those instances on cloud/instance route leads to 500 error and this trace in the API :
