IBX-111: Injected RequestStack into ExposedRoutesExtractor

[alongosz]

Question	Answer
JIRA issue	IBX-111
Type	bug
Target version	eZ Platform v2.5, Ibexa 3.3+
BC breaks	no, internal

This PR fixes ExposedRoutesExtractor by injecting RequestStack instead of Request, which is a correct Symfony way. As this is FOS extension point, the class was never meant to be consumed or extended, therefore adding missing internal annotation.

TODO

• Wait for CI

QA

• IBX-111 steps
• Areas affected by JS routing extraction (maybe Fronted Team can help identify those?)
