It is possible to create several Forum Components

Precondition:

• two users has been created; User1 is loggen in in Browser1 and User2 in Browser2;
• Forum Components wasn't created
• both users open the Components page

Steps to reproduce:

1. User1 create Forum Component
   Actual/Expected: New Forum Component was successfully created
2. User2 create Forum Component

Actual: The 'Error reading 'jcommune' on type org.jtalks.poulpe.web.controller.component.ComponentsVm
Error reading 'jcommune' on type org.jtalks.poulpe.web.controller.component.ComponentsVm
Error reading 'jcommuneVisible' on type org.jtalks.poulpe.web.controller.component.ComponentsVm' message appears.

Also, second Forum Component was created in the database.

When a user navigates to the Components page, 'Error reading 'jcommune' on type org.jtalks.poulpe.web.controller.component.ComponentsVm' message appears.
When a user navigates to any Forum Components, 'query did not return a unique result: 2' message appears. Sections, Branches cannot be created.
So, it is impossible to create sections, branhes, set premissions, etc.

Expected: The system should prevent creating several Components. User2 should receive a message that there is already exist a Forum Component
