Fix restore repo bug, clarify the problem of ForeignIndex (#22776)
Fix #22581
TLDR: #18446 made a mess with ForeignIndex and triggered a design
flaw/bug of #16356, then a quick patch #21271 helped #18446, then the
the bug was re-triggered by #21721 .
Related:
* #16356
* BasicIssueContext

* #18446
* If some issues were dumped without ForeignIndex, then they would be
imported as ForeignIndex=0

* #21271
* It patched the above bug (somewhat), made the issues without
ForeignIndex could have the same value as LocalIndex
* #21721
* It re-triggered the zero-ForeignIndex bug.
ps: I am not sure whether the changes in `GetForeignIndex` are ideal (at
least, now it has almost the same behavior as BasicIssueContext in
#16356), it's just a quick fix. Feel free to edit on this PR directly or
replace it.
