When a master connection is deactivated by user, we set the
autoconnect-blocked reason 'user-request' for the connection and we
propagate the same reason to slaves. Doing so prevents the
autoactivation of slaves when the master is manually activated again,
because the only way to override the 'user-request' blocked reason is
through manual activation of slaves.

Instead what should happen is that the manual deactivation of a master
marks slaves as blocked for failed dependencies. When the master
becomes available again, slaves can autoactivate if the profile allows
it.
