[BUGFIX] Invalid class name to file path conversion

The conversion from a class name such as
tx_extensionname_domain_model_somename to its corresponding PHP file
does not take Extbase naming conventions for the file name. This yields
an wrongly-cased file name which will be validated anyway on case
insensitive file systems.

This wrong conversion may lead to a PHP fatal error
Cannot redeclare class VendorName\Extension\Domain\Model\Somename
