Wrong SASL mechanism is used after upgrade 0.5.2 -> 0.7.0

[DaveLomber]

I used 0.5.2 version and all was good. I use PLAIN SASL mechanism to authenticate

Now I upgraded to 0.7.0 and my code is broken, by some reason the lib started choosing ANONYMOUS mechanism even if I provide the username & password

I did some debugging of this file https://github.com/xmppjs/xmpp.js/blob/master/packages/sasl/index.js#L80
and here is what I got:

supported mech (2) ["ANONYMOUS", "PLAIN"]
offered mech (3) ["PLAIN", "ANONYMOUS", "PLAIN_FAST"]
intersection mech (2) ["ANONYMOUS", "PLAIN"]
chosen mech: ANONYMOUS

so we got here intersection= ["ANONYMOUS", "PLAIN"] and then let mech = intersection[0] and we got ANONYMOUS

Any reason for this? can we somehow set a mechanism we want to use?

As I see it somehow touched here 18984f7

@sonnyp could you provide your feedback here

@DaveLomber thanks for looking into it

I wrongly assumed that a domain would not offer both anonymous and non anonymous mechanisms. I will address this.
