The File Manager will not send images if the ListFiles request is rejected by the module due to encryption

[NicoleYarroch]

Bug Report

If the SDLFileManager sends a ListFiles request and the module rejects it because it needs to be encrypted, the file manager transitions to the error state and no artworks can be sent.

Technically, the SDLFileManager should either 1) not send the ListFiles request until the encryption manager has been setup or 2) it should send the ListFiles request again when the encryption manager has been setup.

A quick workaround would be to check in didEnterStateFetchingInitialList if [error.userInfo[@"resultCode"] isEqualToEnum:SDLResultEncryptionNeeded] and just transition to the SDLFileManagerStateReady if so. This means that the library will waste time re-uploading artworks that already exist on the module but it works as a temporary fix until the SDLFileManager can be reworked to add a dependency on the encryption manager.

Reproduction Steps

1. Configure the module to require encryption for the ListFiles RPC.
2. Connect the SDL app to the module and launch the SDL app.

Expected Behavior

The artworks in the Show request should show up.

Observed Behavior

The artworks for the Show request are never sent to the module due to the SDLFileManager being in the error state.
