Creating a GitLab Issue Room Fails with "issue_iid is invalid"

**Describe the bug**

After setting a personal token for my GitLab instance in a DM room with Hookshot, I try to run `gitlab open issue` to create an issue room, but the command fails. The bot sends "Failed to handle command: undefined" and in the log this appears:

```

**To Reproduce**

1. Set a token for a GitLab instance with Hookshot.
2. Send `gitlab open issue PROJECT`

**Expected behavior**
An issue room is created.

I'm running the latest Docker image, with this config:

```
gitlab:
instances:
ALIAS:
url: GITURL
webhook:
secret: SECRET
publicUrl: WEBHOOKURL
userIdPrefix: _gitlab_
```

From looking at the logged error, hookshot tries to get an issue via the API by the name of "NaN", which fails for obvious reasons. Also, instead of looking for calling the API with the full project path, it only seems to use the group, so the URLs logged are e.g. /api/v4/projects/ONLYGROUPNAME/issues/NaN instead of /api/v4/projects/GROUPNAME/PROJECTNAME/issues/1 which would expect.

Start at the handler for the `gitlab open issue` command and follow the `AdminRoom` and `GitLabClient` flow shown in the logs. Reproduce the command with a personal GitLab token and trace why the issue IID becomes `NaN`; done means the command performs a valid GitLab issue lookup and creates the issue room instead of returning an undefined error.

Written by the indexing model from the issue text.
