Repro steps

1. Create a new schematics project using schematics schematic --name=test-schematic.
2. cd test-schematic
3. npm i
4. npm run build
5. schematics ./src: --list-schematics
6. schematics .:my-full-schematic --name=test

The log given by the failure

N/A

Desired functionality

When authoring a schematic and doing manual testing locally, you do the following:
In schematics ./src: --list-schematics, you reference the collection via ./src:. This is very confusing as I tried a lot of variations before figuring this out, i.e. the following don't work: src:, .:, src/:, src/.:.
In schematics .:my-full-schematic --name=test, you reference the collection via .:.

It would be nice if .: worked for both of these. Can --list-schematics see that the package.json is there and has a collections field just like when running a schematic?

Mention any other details that might be useful

I also saw this with @angular-devkit/schematics-cli@0.9.0-rc.2.
