dont use system composer for autoload checker

[icewind1991]

this ensures that the same composer version is used by everyone (and ci) which prevents issues where a local composer version generates different autoloader files than the one used by ci.

[ChristophWurst]

but how do we make sure everyone has the same local version of the composer.phar? is it always assumed to be the latest? What about stableXYZ branches?

didn't see it was two commits and the changes of the first one are buried in the overall diff

Works :)

ERROR: Please remove or add those files again or inform the release team about those now files to be included or excluded from the release tar ball.

Release team notified.

Please remove the file after the autoloader is dumped when it was downloaded before. No need to add a remove statement to the release script for a file that is only temporarily there in one CI step.
