Do not exit with code 1 on uninstall (--no-dev)

[tobiasbaehr]

Problem/Motivation

When dealerdirect/phpcodesniffer-composer-installer + package which has phpcs rules are uninstalled while composer install --no-dev the dealerdirect/phpcodesniffer-composer-installer exit with the exitcode 1, which breaks a CI.

Expected behaviour

Do nothing in this case.

Actual behaviour

$ composer install --no-interaction --optimize-autoloader --ansi --no-progress --no-dev

@tobiasbaehr Thanks for the detailed report. I'm at a conference right now, but either @Potherca or me will look at this soon.

The main thing which surprises me is that Composer would try to run a plugin which it has just uninstalled.
In that respect, I wonder if this is not a Composer bug instead of a bug in the plugin.

The other thing which surprised me when you originally reported it, is that PHPCS would be reported as unavailable as it is a require-ment of this plugin, so if the plugin is installed, PHPCS should always be available.

Anyway, need to get back to the conference now. I will try to have a look at this later tonight or at some point tomorrow.

[Potherca]

I've created automated reproduction scenarios for this bug (in BASH).

Tomorrow I'll work on a fix.

[Potherca]

I've implemented a fix in MR #104. As soon as it has been reviewed and approved I can deploy a new release to get this fix out the door so @tobiasbaehr can verify it resolves things on his end.

[tobiasbaehr]

I can confirm that #104 works for me.
