EZP-20930: added dependency on hautelook/templated-uri-bundle

Also marked symfony/symfony 2.3.9 as a conflict, since it
introduces a method signature change that doesn't work with
hautelook/templated-uri-bundle.

The change has been reverted on all branches but 2.5, and
a 2.3.10 should be fine.
Merge branch 'feature-EZP-20930-REST_root_resources'
