[Bug]: Undeclared dependency on doctrine/dbal ^3.1.0 | ^4.0.1

Nobody has claimed this yet.

### Preconditions

I've been upgrading old project and I began suddenly getting errors
```
Error: Call to undefined method Doctrine\DBAL\Connection::createSchemaManager()

/home/www/_project_/vendor/liip/test-fixtures-bundle/src/Services/DatabaseTools/ORMDatabaseTool.php:182
```
Later I've found that newest `liip/test-fixtures-bundle 2.7.3` does not work with my current `doctrine/dbal 2.13.9` because `liip/test-fixtures-bundle` has, based on this commit https://github.com/doctrine/dbal/commit/79ee9d0fe4835a670eed2f519228c12e308854a2, undeclared dependency on `doctrine/dbal ^3.1.0 | ^4.0.1`

### Steps to reproduce

Have project with `liip/test-fixtures-bundle 2.7.3` and `doctrine/dbal 2.13.9` and run tests.

### Expected result

Composer should not allow me such combination even install. Alternatively `liip/test-fixtures-bundle` should throw exception that it needs specific version of `doctrine/dbal`.

### Actual result

`Error: Call to undefined method Doctrine\DBAL\Connection::createSchemaManager()`

Start by locating the bundle's dependency declaration and inspect src/Services/DatabaseTools/ORMDatabaseTool.php around line 182. Reproduce the failure with liip/test-fixtures-bundle 2.7.3 and doctrine/dbal 2.13.9; done means the incompatible combination is rejected during installation or reports the required DBAL version clearly.
