Missing trim() function causes error when running php 7.3 on WSL on Windows 10

[pawellen]

Hi,
When running in php 7.3 on WSL on Windows 10 preg_grep returns windows style line endings (\n\r) at the end of line string. To be precise in https://github.com/ongr-io/ElasticsearchBundle/blob/master/DependencyInjection/Compiler/MappingPass.php#L165
got this value:

array:1 [▼
2 => "namespace App\Admin\Common\Controller;\n\r"
]

this causes: _preg_match('/^namespace (.*);$/', $namespaceLine, $match); to fail because of 2 whitespace at end dont match $ i preg.

To fix this issue need to make sure that namespace does not have any whitesapces so in
https://github.com/ongr-io/ElasticsearchBundle/blob/master/DependencyInjection/Compiler/MappingPass.php#L166 please add trim:
$namespaceLine = trim(array_shift($lines));

Please help :)
