Connects to postgres, but fails to run other commands

[daneoshiga]

After the fix in #31 I could connect to postgres databases, but now, after generating the stellar.yml, I can't run any command, all of them gives me database does not exist.

For example:
PostgreSQL: postgresql://localhost:5432/
MySQL: mysql+pymysql://root@localhost/: postgresql://user@localhost:5432/database
Please enter your project name (used internally, eg. sgro) [sgro]: 
Wrote stellar.yaml

Then, running stellar snapshot (or any other):

Traceback (...)
sqlalchemy.exc.OperationalError: (OperationalError) FATAL:  database "user" does not exist
None None

This is related to issue #47. Everything should work after you run init again with the new version of stellar.
