`docker ps` change when both `--quiet` and `--format` options are passed in

[galooph]

Ran into a problem where ce-dev start would spin up the first container successfully (a db one), then spit out WARNING: Ignoring custom format, because both --format and --quiet are set. The second (web) container wasn't started.

Looking at docker/cli#3666, docker ps behaviour has changed, so that when --quiet is passed as well as --format, quiet takes precedence and format is ignored.

Looks like there are two occurrences of this in ce-dev.

As a quick, local, fix I removed the --quiet from /opt/ce-dev/lib/base-cmd-abstract.js, which did the trick.

This should be fixed in v1.2.1.
