Title: Fix get transactions

When the results returned by the API is just one the gem was crashing
due to it was expecting an array and
`response.body['MSG_S']['LISTADOMOVSCTA']['E']` contained a `Hash`.

To fix this I just checked the three scenarios:
- Empty transactions (nil)
- Single transaction (Hash)
- Multiple transactions (Array)
