Show popup when device is not targeted. 

When someone is sending a pfs message to us but did not include our own
device, a pop up is shown propmting the user to connect with the user.

The reason for receiving messages that are not targeting our devices are
various:

1) The account was just recovered (which means it is a new installation
id)
2) More than 3 devices are in use (we only keep max 3 devices in sync)
3) The sender has used an old bundle which does not include the current
device

Eventually we will reduce the likelihood of this scenario happening, but
we can't dismiss it completely.

It's only enabled when PFS is enabled.
