Automatic Fixes: Be more robust against alias targets

[martis42]

Due to the aspect working on the resolved alias targets but buildozer working on the plain BUILD files alias targets are a problem.
buildozer can't work directly with the targets from the report files, since they don't match the content of the BUILD in case of aliased targets.

However, buildozer can query the content of BUILD files. Maybe we are able to find the targets corresponding to the content of the report file.
