`alias_dsn` crashes when the password contains a comma `,`.

[ynn]

My ~/.myclirc has this:

[alias_dsn]
test_1 = mysql://user:password@localhost:3306/db
test_2 = mysql://user:,@localhost:3306/db

The first alias works:

$ mycli -D test_1
(2003, "Can't connect to MySQL server on 'localhost' ([Errno 61] Connection refused)")

The second alias crashes:

$ mycli -D test_2

Quoting worked like a charm:

[alias_dsn]
test_1 = mysql://user:password@localhost:3306/db
test_2 = 'mysql://user:,@localhost:3306/db'
