Encrypted RPCs that fail because encryption isn't set up don't call back

[joeljfischer]

Bug Report

If RPC service encryption is set up, attempting to send an RPC request before encryption is set up will result in the handler never being called. This can cause managers to hang when setting up if, for example, PutFile is encrypted. This results in the app being totally inoperable.

Reproduction Steps

1. Set up RPC encryption on Core and make PutFile require encryption
2. Connect an app that supports RPC encryption

Expected Behavior

The app successfully sets up, or at least is operable after failing some part

Observed Behavior

The app is entirely broken due to SDLFileManager hanging when attempting to send the app icon. This fails due to RPC encryption not being set up yet and the handler is never called, leaving the operation and manager to hang.
