Resolve ml-queries from directory

Previously, there was a bug where quick eval queries would crash when
the eval snippet is in a library file.

The problem was that the `codeql resolve queries` command fails when
passed a library file. The fix is to avoid passing the library file at
all. Instead, pass the directory. This is safe because the resolve
queries command only needs to know which query pack the file is
contained in. Passing in the parent directory is the same as passing in
a file in this particular case.
