Issue with getting all projects a user has access to

[Mesverrum]

This is a Grafana SE working with CME who are heavy users of the GCL plugin. They have a large number of projects that users are associated with and have seen that the Project ID field drop down is limited to 36 projects, but their users are in more than that. If they manually set a Project ID number it will work, so the limitation seems to be just with getting the drop down to populate with larger numbers of results.
