Looks like you're running into some issues centering around how the APIs around users changed. See https://scriptrunner.adaptavist.com/latest/jira/releases/UpgradingToJira7.html#_user_replaced_with_applicationuser

I'd recommend either changing your helper methods to take/return an ApplicationUser object or just use 'def'. 

For example:

private ApplicationUser getUser(user) {
    def userManager = ComponentAccessor.userManager
    userManager.getUserByName(user)
}

You may notice that I'm using the userManager instead of userUtil.getUserObject. That's simply because the getUserObject was deprecated in 7.0, but it will still work.
