[BUG/TEST 2/2] t3501: Expose addinfo_cache error message in cherry-pick

[Stephen Boyd <sboyd@codeaurora.org>]

I encountered a mysterious error message while doing some
cherry-picking into a dirty tree. In this case, the working tree
was dirty with changes to two files that had been renamed, we'll
call them 'file and 'otherfile'. The change I wanted to
cherry-pick was made along a branch before the rename to 'file'.
When I cherry-picked the change from the other branch without the
rename to my current branch with the rename, the change applied
cleanly and the dirty bits were committed but a mysterious error
message was printed indicating something went wrong with the file
that was still dirty after the cherry-pick.

	error: addinfo_cache failed for path 'otherfile'

I suspect this error message shouldn't be printed, so recreate
the problem in t3501 so that it can be fixed.
