`dx component add` does not correctly suggests --package flag when in workspace

[matthiasbeyer]

Problem

When trying to dx component add in a workspace with multiple binaries, the --package flag is suggested. It would be very nice to understand at what position that flag is expected:

$ dx components add progress

You need to either run dx from inside a binary crate or specify a binary package to build with the `--package` flag. Try building again with one of the binary packages in the workspace:
