Monolog Bridge 2.8 cannot be used with HTTP Kernel 3.0 as the LoggerInterface is not defined anymore. That's a problem for the Silex Skeleton for instance.

59ffd04 added a conflict between Monolog bridge 2.8 and HTTP Kernel 3.0+

Caused by symfony#18705, it is impossible to install v3.0.6 of symfony/monolog-bridge
together with v3.0.6 of symfony/http-kernel.

The intention of symfony#18705 "added a conflict between Monolog bridge 2.8 and
HTTP Kernel 3.0+" was to prevent installing symfony/monolog-bridge from the
3.0 series with http-kernel from the 2.8 series of symfony. While this now
works correctly in 2.8.6, exactly the opposite behavior was reached for 3.0.6.

This commit resolves this issue.

# How to reproduce
- Create a test directory and change into it - e.g. with `mkdir /tmp/reproduce-symfony-18745 && cd /tmp/reproduce-symfony-18745`
- Add the following composer.json to this test directory
```
{
   "require": {
     "symfony/monolog-bridge": "3.0.6",
     "symfony/http-kernel": "3.0.6"
  }
}
```
- Run `composer install` from the test directory

## Expected behavior
Composer installs symfony/monolog-bridge and symfony/http-kernel (together with their dependencies).

## Actual behavior
Composer fails with the following error messages:
```
#:/tmp/reproduce-symfony-18745$ composer install
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony/monolog-bridge 3.0.6 -> satisfiable by symfony/monolog-bridge[v3.0.6].
    - symfony/http-kernel v3.0.6 conflicts with symfony/monolog-bridge[v3.0.6].
    - Installation request for symfony/http-kernel 3.0.6 -> satisfiable by symfony/http-kernel[v3.0.6].
