REDACT_FIELDS are present if they're not sent

[rafaqueque]

Example:

http http://localhost:4000/token username=test account=test

The information sent to bugsnag is the following:

query_params = %{username: "test", account: "test", password: "[REDACTED]"}

It should not put the password all the time in the query_params because it leads to a more difficult debugging, for example, a client that didn't send the correct query_params and so on.
