Fix a null pointer dereference in validateaddress with -disablewallet. Also add a regression testcase.

Problem reported here: #6963 (comment)

I think this needs to be backported to 0.11 as well.

Nice catch! I was also looking for the NULL pointer access... we need to be careful by always keeping in mind: #ifdef ENABLE_WALLET != pwalletMain available.

Good news: the issue doesn't exist in 0.11 (and hence not in any released version)

This problem was introduced in 506bae3 (#6262) by @dexX7 . The code used to check for ISMINE_*, which can only be ISMINE_NO if there is no wallet, but that check was removed there.

@jlopp Did it fix your issue? (I still don't see how this can cause a SIGILL in OpenSSL)

@laanwj Yes, I confirmed that my node no longer crashes after issuing the validateaddress command. As for the other errors I had posted in my comments, those were errors that the debugger was throwing immediately upon trying to run bitcoind, not upon calling validateaddress.
