main: return error if user requests addr or tx index while pruned

Browse Source 
This change is part of the effort to add pruning support to btcd.

It's not possible to generate the addr or tx indexes from scratch if the
block storage had been pruned previously as it's missing the block data.
When the user asks to create these indexes, tell them it's not possible
and the only way it's possible is if they delete and start anew.
