plugin-manager: relaunch probing when suggestion comes to deferred tasks

Browse Source 
If a port support task was deferred until suggested, do not assume that the
suggested plugin actually supports the port, instead re-launch support check.

This covers the cases where a net port appears in a modem which only supports
AT ports (e.g. Nokia case).
