[WIP] fix version constraint to doctrine/phpcr-odm package

The setFallbackLocales() method in the locale chooser of the doctrine/phpcr-odm package was first added on March 1st. Thus, 1.1.0-RC1 or higher of doctrine/phpcr-odm is required.

Unfortunately, this proposed change doesn't solve the issue. As you can see [here](https://travis-ci.org/xabbuh/SeoBundle/jobs/27011434), Composer isn't able to resolve the dependencies.
just tried and changing this line to 1.1.* makes composer install. feels like there is a bug with composer though, i would expect this line to install 1.1.0 (or 3.0 for that matter, there is no upper boundary)
