optimize-use: Duplicate imports

[tobyS]

I usually reference \RuntimeException absolutely without importing it. The optimize-use attempts to fix this, but creates duplicate imports, e.g.:

--- a/test/features/bootstrap/FeatureContext.php
+++ b/test/features/bootstrap/FeatureContext.php

I would love to have a look at this - the other issue is related. But I have a lot of other stuff todo before this. So if it's not needed to be fixed asap, I'll do it :)

@pscheit no rush, we just tested this on a large code basis.

this depends on #32, I have another test for it and will send a PR then.
