Teams list

[Mateusz-Dobrzynski]

TO-DO:

• Create a list of teams available at /t/{tournament_id}/teams containing a list of teams assigned to a tournament,
• The list contains a button to create new teams – available only to people with a WriteTeams permission,
• Each entry contains a team name and its shortened name,

How to test:

• Create a new team (by altering the DB manually). The team should be present on the list.
• Rename the team. Its names should be changed on the list and in the DB.
• Log in as a user without a WriteTeams permission.
  • The button for teams creation should not be present in the teams list view.
