Teams: No limit on number of members

[paulbert]

Current Behavior

There is a limit property on the team document that is always set to 12. This sets a limit that disables adding member buttons after the team has 12 or more members (any number of members can be added in the Add Members dialog, but the button is disabled when the team currently has 12 or more).

Desired Behavior

This is controlled by disableAddingMembers in TeamsViewComponent. Let's add a condition that this.team.hasMemberLimit === true to the condition. This will remove the limit for all teams previously created and ones made with the current team creation process, but will give us flexibility in the future to allow teams to create their own limit if needed.
