Handle when there are 0 transactions about transactions

I assume the signature of simple_transaction or its alias create is confusing. This is a good reason to improve it.

It looks like you are passing a tuple for the from_address parameter. For example, the following works:

from transactions import Transactions
alice = 'mhyCaF2HFk7CVwKmyQ8TahgVdjnHSr1pTv'
bob = 'mqXz83H4LCxjf2ie8hYNsTRByvtfV43Pa7'
transactions = Transactions(testnet=True)
tx = transactions.create(alice, (bob, 10000))

but the following:

tx = transactions.create(('', alice), (bob, 10000))

will yield the error:

TypeError: list indices must be integers, not unicode

because the code is expecting a dict, but it got a list, and tried to retrieve the value 'txs' from the list:

[{u'address': u"(''",
  u'limit_txs': 200,
  u'nb_txs': 0,
  u'nb_txs_displayed': 0,
  u'txs': []},
 {u'address': u" 'mhyCaF2HFk7CVwKmyQ8TahgVdjnHSr1pTv')",
  u'limit_txs': 200,
  u'nb_txs': 0,
  u'nb_txs_displayed': 0,
  u'txs': []}]
