Add checkCanceled check on resolving imports path

Imports resolution is a rather time consuming task and doesn't have
 `checkCanceled` on its computation path. So, if a thread is resolving
 imports it will do it until the end of computation, which can lead to
 unnecessary work and some IDE freezes.
