Subflow + GCP nodes

[paack-andreidraghia]

When trying to use a node (Firebase in my concrete case) from inside a sub-flow, it complains with the following issue:

msg : error
"TypeError: Cannot read property 'account' of undefined"

Node version: 2.0.5
Environment: Docker on local machine
Credentials provided via the configuration node.

I believe it cannot access the service account credentials when inside a sub-flow and sees the "account" property of the credentials as undefined.
Just copy-pasting the nodes outside of the flow work perfectly.
