fully_qualified_strict_types breaks header_comment

[mvorisek]

Bug report

It seems fully_qualified_strict_types adds the uses above declare(strict_types=1) leading to header comment duplication by header_comment.

Maybe only a priority issue as declare_strict_types should asserts the declare(strict_types=1) is always the first statement after <?php.

fully_qualified_strict_types should be however fixed too to add the uses after the strict declare statement.

Quick help welcomed as the last PHP CS Fixer updated started to add a lot of use imports but the duplicated header is never removed by any fixer!

Even breaking code when shebang is present!

with such diff/code, MultilineWhitespaceBeforeSemicolonsFixer fixer crashes:

This must be improved here, I did not take no-namespace files into consideration 😕. Probably imports should be inserted before the first statement other than declare.
