getGroupsForUser returns incorrect results for role names containing periods

[mfen]

Role name arguments supplied to getGroupsForUser have periods replaced by underscores, when period replacing appears to be intended for group names only.

In such cases, getGroupsForUser returns the groups for a different, similarly named role actually containing underscores instead of periods, or, if such a role does not exist, an empty array.

Roles.createRole('users.view');
Roles.addUsersToRoles(user._id, 'users.view', group);
Roles.getGroupsForUser(user._id, 'users.view'); // Returns []

Second that, just stumbled on this.
