fix filterByDistanceFrom(..)

[mpoiriert]

The missing variable from the template have been fixe.

I don't get your patch..

It's concerning the pull request 29

In MySQL you can't use WHERE with a generated column, so using filterByDistanceFrom with the new 'Distance'-column crashes:
"Unable to execute SELECT statement
[SELECT *, ABS(6371 * ACOS(x * COS(RADIANS(lat)) * COS(RADIANS(lng) - y) + z * SIN(RADIANS(lat)))) AS Distance FROM table WHERE Distance < :p1]
[wrapped: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Distance' in 'where clause']"

Even the HAVING-clause, which works with newer MySQL versions could be used in this context, does not work with older versions.
So due to compatibility issues I think this file should be reverted (even if that means duplicated code...)

I just properly fix it starting from the change of dominik (his pull request wasn't passing travis).

If there is any reason why you can't accept the pull request let me know I might have time to adjust it. I starting to use this behavior in a symfony2 project and I prefer to use the main repo than overriding it with a fork...
