[Clearance | execution plan] If a user cannot execute a test case, have a warning message by clicking on the "via popup" button

Affected version : version TM 6.0.1, 6.1.0.RC1

Steps to reproduce

• Have an authorized user on a project with the "tester" profile have a team, with the user as a member, and the guest profile on the same project

= cumulative guest and tester rights on the project

• Have 2 test cases in an execution plan, one of which is assigned to the user
• Login with the user
• go to execution plan

Observed behaviour

the "via popup" button is active and clickable, and a white popup is displayed.

To maintain consistency with the "new execution" button, the popup should display a rights warning message

Expected result

the popup should display a rights warning message

For ITPIs assigned to the user, the "tester" behavior applies:

• The user can click on every menu items and create executions => this is the current behavior

For ITPIs not assigned to the user, the "guest" behavior applies:

• The "New execution" and "with the popup" item should be grayed out (no execution is created)
• The user can still view the execution history
