[dataexchange] Fixing Deadlock on Reconnect

[onelapahead]

Proposed changes

If you restart a DX FF is connected to, it will cause FF to initialize and reconnect to it.

But with the recent #1652, we want to check the node's identity status relative to the DX config, but we wrongfully checked if the DX plugin was initialized - causing a deadlock since during reconnect we are holding the lock that re-initializes the plugin 🔁 .

It's safe to check the node identity status when we are not initialized since it is the same thing as GetEndpointInfo with some extra work.
