resolves #9014
resolves #9117

Enhance for following scenarios:

  1. Target without path specified and cannot be found.
  2. Target without path specified and cannot be found, but a file
    exists at the commonly wrong path, e.g. example/a.rs, bench/b.rs.
  3. Found multiple candidate files and cannot infer which to use.

For the suggestion in the thread in #9116, I can't see any feasible way to list potential candidates without addditional I/O checking file existences. This PR is the best effort I can think of at this time. Feel free to comment. Thanks!
