Check caching mechanism for Bosch IoT Suite generator postman/dev-console option

[kolotu]

The Caching mechanism can pickup the wrong attachment in some cases.

/api/v1/generators/boschiotsuite/models/org.eclipse.vorto.tutorials:RaspberryPi:1.0.0?provision=true&requestBodyOnly=true

for this generator it's for the provisioning string
for the postman collection it's

so it seems to get confused with the two tags with the same name here.

We could add another query parameter to the postman option (output=postman) or ensure that it's evaluated that there are either 1 or 2 tags.

This bug could also be already fixed and the data on this specific model was just outdated.
