BaseReceivePack: Add hasReceivedPack method

The getPackSize method will throw IllegalStateException if it is
called when the pack size is not set. This is the case for example
when the received commands are all DELETE and there is no pack.

Add a new method hasReceivedPack that can be called prior to calling
getPackSize, to avoid causing the IllegalStateException.

See [1] for context.
