FIX Rename file to match class name

Fix for #127

Just checking if this can be merged?

There was a broken behat test, possibly related to the use of old travis shared config. I tried rerunning the individual build though it still uses the old config. I've just retriggered a build that will use an updated shared config by git undoing the last commit and re-commiting. It creates a new hash though the code is the same as what was approved.

Behat test passed on rerun

@obj63mc I've tagged 2.3.6 and 2.4.2 for you which both contain this fix
