Rector version	dev-master@ca35301
Installed as	Online rector

This might be an upstream issue

When rector checks the given minimal testcase below, the second route annotation will be modified.
The quotes around the string parameter name get removed which is wrong, because

1. No rector is modifying it (parser issue?)
2. The first route, though being identical is not touched (inconsistency)
3. The parameter is a string and as such should not be touched at all (null vs "null" is obviously a difference)

Expected Behaviour

Code should not get modified at all.

@TomasVotruba Is the close/relation correct? #4454 is a merged PR from end of october.
