I was not able to reproduce the bug on a fresh installation of 15.04.
It looks like this issue happens when you upgrade the package from ubuntu4 to ubuntu5.
I think that the following workaround may resolve the issue:
$ sudo rm /etc/systemd/system/mysql.service
After running this command you (theoretically) should be able to purge and install the package w/o any issue.
Please let us now if it helps you or not.
