Cannot connect, due to recent changes in connect string, user and password handling

[julianhyde]

In the vote thread for the 1.9 rc0 release, @arina-ielchiieva reports breakage:

After upgrade, Drill unable to connect to SqlLine, shows the following error:

Usage: connect [-no-np] [-p property value]* [username] [password] [driver]

This is very likely caused by the fix to #326.

@snuyanzin what do you think should be done to fix the regression so we can proceed with the release?

[snuyanzin]

It seems I found a solution and added a junittest similar to your case. However it would be nice if you also check your case @arina-ielchiieva

Fixed in ee2d81d. (That commit says that it fixes #326, because we replaced the previous commit that fixed that issue.)
