fix problem when double clicking on "private"

[cylwin]

Hello,

If we refresh the view when the clearance have not changed, there is a freeze and we can't change the clareance again. This commit fix this issue. Maybe it's not the good way to fix the problem, but it works.

Bye

In fact you should ensure that clearance is not private instead of testing if it's public. Because there is a third case: sharing with a list of users.

not private == empty array ?

You should use the dedicated function isPrivateClearance:

It's still wrong you should ensure that clearance is not private instead of testing if it's public. Because there is a third case: sharing with a list of users.
