wallet: Reset BerkeleyDB handle after connection fails

According to the BerkeleyDB docs, the DbEnv handle may not be accessed
after close() has been called. This change ensures that we create a new
handle after close() is called. This avoids a segfault when the first
connection attempt fails and then a second connection attempt tries to
call open() on the already closed DbEnv handle.
