Work Around Google's WORKSPACE_ALL_ADMIN_GROUP

[rlxdev]

🗣 Description

Google is returning an actual group name, WORKSPACE_ALL_ADMIN_GROUP, in some cases as part of the policy API results. This does not conform to the documented format of groups/<group-id>, and was causing the ScubaGoggles code to crash when encountering this unexpected value. Based on Google's response, a work-around has been put into place to "tolerate" non-conforming group values.

Closes #572

🧪 Testing

This has been tested in the debugger by simulating the WORKSPACE_ALL_ADMIN_GROUP group value in the Google results, as our tenant (scubagws.org) does not currently return this value. The user who reported this issue also tested the proposed change and has confirmed that the change resolves the issue.
