pkgdev bugs --edit-graph breaks filing bugs that depend on existing bugs.

[eli-schwartz]

With debug traces:

     def file_bug(
         self,
         api_key: str,
         auto_cc_arches: frozenset[str],
         block_bugs: list[int],
         modified_repo: multiplex.tree,
         observer=None,
     ) -> int:
+         print(f'filing bug for: {self.pkgs=}, {self.bugno=}, {self.edges=}')
         if self.bugno is not None:
             return self.bugno
         for dep in self.edges:
             if dep.bugno is None:
                 dep.file_bug(api_key, auto_cc_arches, (), modified_repo, observer)

Broken (no edits made to the resulting graph -- I use it purely to read and review what I'm about to submit):

(Given pkgdev doesn't seem to verify that existing bugs are for a PVR that successfully completes the depgraph for the bug you want to file, one could put forth an argument that this ticket is not an error report, but rather a success report. Still it does appear the current behavior is unintentional.)
