popovers: Hide "Send private message" if user not have PM permissions.

If an organization does not allow to send private messages, it will
not display the "Send private message" option in the profile popover.

Currently, there are only two options in settings, first is to allow
every type of user to send PMs and the second is to disable send PMs
for everyone, hence I am just checking that the second option is not
selected.

Fixes: #21888
