IntelliJ sends us the file and offset of the declaration of the element,
not the file and offset where the element is referenced (and where the
user actually requested search). It uses navigation information to do
this. Unfortunately this means that in the most case the unit that
defines the element is not a priority one, so we have to resolse it
from scratch. But we know that we are always given the name offset,
so we can look first into the element model and avoid performing
expensive unit resolution.
If the search is not successful, or the file is a priority one,
we use resolved unit anyway.
