Removes escape character of an alias when setting target

[pderaaij]

This resolves #695 and additionally also provides better input for the graph rendering. When setting the target, the escape character is now explicitly removed.

@riccardoferretti I can use your help here. I am stuck getting the tests stable. For whatever reason, the tests are flaky and randomly fail due to disposed editors. I don't understand what is happening here. It seems to be caused from another test, but I can't find a consistent relation. Would appreciate if you can have a look at this. Perhaps you find the right thing that's causing this.

@riccardoferretti Looks like I found the issue. The problems seem to be caused by the after save wikilink reference definition generation. As it's not needed for these tests, I am disabling them via updating the configuration. On the hand, this could be the default behaviour for all tests.

You are a hero for finding this, I was not looking anywhere near that, I thought the issue was in the test setup/teardown. 🎉🎉🎉

LGTM!
