Unable to resolve virtual package with providers = true options

Composer is unable to resolve packages mirrored by generated Satis repository.
Installation works as expected without satis-repository in composer.json or if repository is built without `"providers": true` option.

Reproduction steps:
run `satis build` with satis.json:
```json
{
"name": "Repository",
"homepage": "http://localhost:4170",
"repositories": [
{
"type": "composer",
"url": "https://packagist.org"
}
],
"require": {
"fig/http-message-util": "1.1.3",
"psr/container": "1.0.0",
"psr/http-factory": "1.0.0",
"psr/http-message": "1.0.1",
"psr/http-server-handler": "1.0.1",
"psr/http-server-middleware": "1.0.1",
"zendframework/zend-diactoros": "2.1.1",
"zendframework/zend-escaper": "2.6.0",
"zendframework/zend-expressive": "3.2.1",
"zendframework/zend-expressive-router": "3.1.0",
"zendframework/zend-expressive-template": "2.0.0",
"zendframework/zend-httphandlerrunner": "1.1.0",
"zendframework/zend-stratigility": "3.1.0"
},
"providers": true,
"output-dir": "./packages",
"archive": {
"directory": "dist",
"format": "zip",
"prefix-url": "http://localhost:4170",
"skip-dev": true
}
}
```

Create empty folder with composer.json:
```json
{
"name": "example/template",
"description": "Package description",
"type": "project",
"license": "MIT",
"repositories": [
{
"type": "composer",
"url": "http://localhost:4170/"
}, {
"packagist": false
}
],
"require": {
"zendframework/zend-diactoros": "^2.0",
"zendframework/zend-expressive": "^3.2"
},
"config": {
"secure-http": false,
"sort-packages": true,
"preferred-install": {
"*": "dist"
}
}
}
```

Run `composer update -vvv`.
Output:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- zendframework/zend-httphandlerrunner 1.1.0 requires psr/http-message-implementation ^1.0 -> no matching package found.
- zendframework/zend-expressive 3.2.1 requires zendframework/zend-httphandlerrunner ^1.0.1 -> satisfiable by zendframework/zend-httphandlerrunner[1.1.0].
- Installation request for zendframework/zend-expressive ^3.2 -> satisfiable by zendframework/zend-expressive[3.2.1].

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see for more details.
- It's a private package and you forgot to add a custom repository to find it
