replace getPropertyAccessor with createPropertyAccessor

[ghost]

getPropertyAccessor was deprecated in Symfony 2.3. This commit solves
a deprecation warning that shows up in Symfony 2.7.

Then you should also update the minimum "symfony/property-access" version to 2.3.
"symfony/property-access": "~2.3"

ah, i figured that'd already be there. I'll add that

submitted as #114, as i think that change stands alone

👍 since this needs to be done in order to remove the deprecation warnings in 2.7

But shouldn't the version change for symfony/property-access be part of this PR? This version might still (depending on when this or the other PR is merged) result in people upgrading to it while using symfony <= 2.2.

Maybe even bumping the version might be in order?
